You can put this solution on YOUR website! For finding the side of any triangle, use the Pythagorean theorem: where a^2+b^2=c^2.
You already have two of the numbers provided for you. One side is 15, the other is 20.
15^2+20^2=c^2
You are trying to determine the length of the other side. It could either be a, b, or c..your choice. Since you did not specify which..I just put them in the order you gave them.
225+400=c^2
c^2=625
c=(square root of 625)
c=25
So your other side, or hypotenuse is 25.
