The hypotenuse of an isosceles triangles measures 10 inches long. What is the length of one leg of the triangle?

Answers

Because this triangle is isosceles, its legs are equal, so we can write using Pythagorean theorem

a² +a² = 10²
2a²= 10²
a² = 10²/2
a=√(10²)/√2 =10/√2 = 10√2/(√2√2)= 10√2/2 =5√2

a= 5√2 (inch)

Answer is 5√2 inches.

Answer:

10/√2
