Question

Anybody know the answer?

Answer 1

So since its a right triangle, we can use the pythagorean theorem, which is
`leg^2+leg^2=hypotenuse^2` . Since we know that 2 and 3 are our legs and x is our hypotenuse, we can solve the equation as such:

`2^2+3^2=x^2\\ 4+9=x^2\\ 13=x^2\\ √(13)=x`

Since √13 can't be further simplified, that is your final answer.
