(b) the volume of the prism. (c) the total surface area of the prism. The in-radius of an equilateral traingle is of length 3 cm. A. The base of a right prism is a right angled triangle. In the equilateral triangle ABC of side «a»: ⇒ S = ½.a.h …. The height of an equilateral triangle is 4 StartRoot 3 EndRoot. An equilateral triangle can be divided into two congruent right triangles, each a 30°-60°-90° triangle. Here are the formulas for area, altitude, perimeter, and semi-perimeter of an equilateral triangle. Find the total surface area of the pyramid in . - 20729830 ∴ Height 3 = in radius ∴ Height = Median .. Geometry. An equilateral triangle has a height of 26 inches. Area of equilateral triangle. Best Answer . XY is parallel to BC, XP is parallel to AC and YQ is parallel to AB. Find the perpendicular height of an equilateral triangle whose side is 12 cm - 32791679 The measure of the base of the right angled triangle is 3 m and its height 4 m. If the height of the prism is 7 m. then find (a) the number fo edges of the prism. Area of a triangle = 1/2 * b * h Let the sides of the equilateral triangle be 2x and form a right-angled triangle by drawing a vertical line down the middle. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. This problem has been solved! Important Solutions 1578. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. The internal angles of the equilateral triangle are also the same, that is, 60 degrees. Textbook Solutions 5346. And let AD is an altitude on BC. Equilateral triangles have sides of equal length, with angles of 60°. In an equilateral triangle find the length of a radius if the length of a side is 12. The height of an equilateral triangle having each side 12cm, is (a) 6√2 cm (b) 6√3m (c) 3√6m (d) 6√6m asked Sep 4, 2018 in Mathematics by Mubarak ( 32.5k points) triangles Mathematics, 21.06.2019 17:20. 7:22 100+ LIKES Find the Height of an Equilateral Triangle Having Side 2a. Find the length of height = bisector = median if given side ( L ) : height bisector and median of an equilateral triangle : = Digit 1 2 4 6 10 F Given: ABC is an equilateral triangle. Applying Pythagoras theorem in right-angled triangle ABD, we get: Hence, the height of the given triangle is 6√3 cm. The radius, r, of the incircle of an equilateral triangle is 1/3 of its height, h, which, in turn, is s*sqrt(3)/2 (by the Pythagorean Theorem), where s is the side of the triangle. In the given figure, ABC is an equilateral triangle of side length 30 cm. An equilateral triangle with side length 12 cm is shown in the diagram, work out the height of the triangle. A point within an equilateral triangle whose perimeter is 30 m is 2 m from one side and 3 m from another side. A point is selected at random inside an equilateral triangle. An angle bisector of a triangle divides the opposite side of the triangle into segments 6 cm and 5 cm long. hence each slant side = 12cm to find the height of the triangle : use Pythagoras’ Theorem (A^2 + B^2 = C^2) Therefore, BD = 1/2 x BC = 6 cm, Now, In ∆ADB, using Pythagoras theorem, we have, (Perpendicular)2 + (Base)2 = (Hypotenuse)2, Hence, the height of an equilateral triangle is 6√3 cm. If an equilateral triangle is circumscribed about a circle of radius 10 cm, determine the side of the triangle. What is the perimeter of the equilateral triangle? Therefore, BD = 1/2 x BC = 6 cm. 1 answer. An equilateral triangle has three congruent sides, and is also an equiangular triangle with three congruent angles that each meansure 60 degrees. Find the height of an equilateral triangle with sides of 12 units. Answers: 2 Show answers Another question on Mathematics. 64.12 cm; C. 36.44 cm; D. 32.10 cm; Problem Answer: The side of the equilateral triangle is 34.64 cm. In an equilateral triangle ABC, the side BC is trisected at D. Then AD^2 is equal to. 1. See the answer. To find the height we divide the triangle into two special 30 - 60 - 90 right triangles by drawing a line from one corner to the center of the opposite side. A second side of the triangle is 6.9 cm long. To find the height, we can draw an altitude to one of the sides in order to split the triangle into two equal 30-60-90 triangles. Aboat costs 19200 and decreases in value by 12% per year. Now, In ∆ADB, using Pythagoras theorem, we have. Notice that that 6 is the value of "s", across from the 30 degree angle at the top. Lets assume a, b, c are the sudes of triangle.

Solution Show Solution Since, ABC is an equilateral triangle, CD is the perpendicular bisector of AB. Maharashtra State Board SSC (Marathi Semi-English) 10th Standard [इयत्ता १० वी] Question Papers 156. From this point a perpendicular is dropped to each side. In a equilateral triangle, all sides are equal. (Perpendicular)2 + (Base)2 = … 34.64 cm; B. What is the altitude of an equilateral triangle whose side is 12cm? asked Mar 8, 2016 in Class X Maths by bhai Basic (90 points) +1 vote. The base of a right pyramid is an equilateral triangle, each side of which is cm long and its height is 4 cm. Question Bank Solutions 3888. The decimal answer is an estimate. a = b = c = 12 cm Now we use the Pythagorean theorem in order to find the height of the triangle. As the name suggests, ‘equi’ means Equal, an equilateral triangle is the one where all sides are equal and have an equal angle. Since all the sides are of equal length, the side that is the hypotenuse of the right triangle has a length 2x. That means the bottom side of 12 cm is split into 6 cm on the left and 6 cm on the right. 6√3 cm. The area of an equilateral triangle (S) is calculated from the following figure: We know that the area of a triangle is ½(base x height). Find its distance from third side.

Find the length of height = bisector = median if given side ( L ) : height bisector and median of an equilateral triangle : = Digit 1 2 4 6 10 F Given: ABC is an equilateral triangle. Applying Pythagoras theorem in right-angled triangle ABD, we get: Hence, the height of the given triangle is 6√3 cm. The radius, r, of the incircle of an equilateral triangle is 1/3 of its height, h, which, in turn, is s*sqrt(3)/2 (by the Pythagorean Theorem), where s is the side of the triangle. In the given figure, ABC is an equilateral triangle of side length 30 cm. An equilateral triangle with side length 12 cm is shown in the diagram, work out the height of the triangle. A point within an equilateral triangle whose perimeter is 30 m is 2 m from one side and 3 m from another side. A point is selected at random inside an equilateral triangle. An angle bisector of a triangle divides the opposite side of the triangle into segments 6 cm and 5 cm long. hence each slant side = 12cm to find the height of the triangle : use Pythagoras’ Theorem (A^2 + B^2 = C^2) Therefore, BD = 1/2 x BC = 6 cm, Now, In ∆ADB, using Pythagoras theorem, we have, (Perpendicular)2 + (Base)2 = (Hypotenuse)2, Hence, the height of an equilateral triangle is 6√3 cm. If an equilateral triangle is circumscribed about a circle of radius 10 cm, determine the side of the triangle. What is the perimeter of the equilateral triangle? Therefore, BD = 1/2 x BC = 6 cm. 1 answer. An equilateral triangle has three congruent sides, and is also an equiangular triangle with three congruent angles that each meansure 60 degrees.

Answers: 2 Show answers Another question on Mathematics. 64.12 cm; C. 36.44 cm; D. 32.10 cm; Problem Answer: The side of the equilateral triangle is 34.64 cm. In an equilateral triangle ABC, the side BC is trisected at D. Then AD^2 is equal to. 1. See the answer. To find the height we divide the triangle into two special 30 - 60 - 90 right triangles by drawing a line from one corner to the center of the opposite side. A second side of the triangle is 6.9 cm long. To find the height, we can draw an altitude to one of the sides in order to split the triangle into two equal 30-60-90 triangles. Aboat costs 19200 and decreases in value by 12% per year. Now, In ∆ADB, using Pythagoras theorem, we have. Notice that that 6 is the value of "s", across from the 30 degree angle at the top. Lets assume a, b, c are the sudes of triangle.
