Find the hypotenuse c of the right triangle a=15,b=20

To find the hypotenuse, you have to use a squared + b squared = c squared

So it would be,

15 squared + 20 squared = c squared

225 + 400 = 625

Since the answer is squared you have to find the square root

The square root of 625 is 25

So the c-=25

15 write your number
