Question

Find the value of x in the isosceles triangle.

Answer 1

Answer:

Step-by-step explanation:

The total length of triangle is 40 in. The length of the right triangle is the total length divided by 2 which 40/2 = 20.

We have 2 right triangles. We can use the pythagorean theorem to solve for x.

a^2 + b^2 = c^2

x^2 + 20^2 = 25^2

x^2 + 400 = 625

      - 400  - 400

x^2 = 225

x = 15
