Question

The figure shows a square and 4 congruent isosceles triangles. If the length of leg x is 12 feet, what is the length in feet of the hypotenuse of each triangle?​

Answer 1

hypotenuse = 13 feet

Explanation:

base of triangle is 10 feet

x=12 feet

1/2 base =5 feet

use Pythagorean theorem

5^2+12^2=hypotenuse^2

25+144=169

sq root 169=13
