Question

If the hypotunes of an isosceles right triangle is 128 cm2 find the length of each side

Answer 1

If the square of the hypotenuse of an isosceles right triangle is 128 cm^2, find the length of each side.
---------------------------------------------------------- 

 +  = 128,  = 128,  =  = 64, x =  = 8 cm.

Answer 2

Answer:

8 cm

Step-by-step explanation:

Let the equal sides of the triangle be x

(since it is a isosceles triangle)

We can use use Pythagoras theorem for solving this problem.

(hypotenuse)^2 = (base)^2 + (perpendicular)^2

128 = x^2 + x^2 (since it is a isosceles triangle)

128 = 2x ^2

128/2 = x^2

x^2 = 64

x = 8 cm
