Question

A side of an isosceles right angle triangle is x find its hypotenuse
​

Answer 1

Step-by-step explanation:

side of isosceles triangle =x

so sides of triangle are x , x , hypotenuse

by Pythagoras theorem,

x^2 + x^2 =hypotenuse^2

2x^2 = hypotenuse^2

by taking square roots on both sides,

(under root 2) x = hypotenuse
