3 yd

4 yd

What is the length of the hypotenuse?

5 yd

Step-by-step explanation:

we can use this formula

leg^2+leg^2 = hypotenuse ^2

if you plug it in, it should look like this, (let x be the hypotenuse since we are trying to find it)

3^2 + 4^2 = x^2

so if you square it, it should look like this

9+16 = x^2

then its

25=x^2

we have to bring the square to the other side, so in order to get rid of it we have to put a radical on top of 25

then you have to find two of the same numbers that times to equal 25 which is 5

so x=5
