Question

an isosceles right triangle has a hypotenuse of 18cm . find the other two sides .​

Answer 1

Step-by-step explanation:

let the isosceles triangle of the side are the = x

x+x+ hypotenuse

use the Pythagoras theorem

x square + x square = 18 square

2x square=324

x square=324/2

x square=162

x=√162

Answer 2

Answer:

13cm

Step-by-step explanation:

An isosceles triangle has 2 sides equal

One side is 18cm

Let other two sides be x

Then,

(by Pythagoras theorem)

Ac²=bc²+ab²

X²=18²+x²

2x²=18²

2x²=324

X²=324/2

X=13
