you'd do 15^2 + 10^2

Then take that answer and square root it.

You should also probably round to the neartest whoole number if you get a decimal.

Well do you know the pythagorean theorum?? It say that the base squared + the height squared should equal the slope squared. So your going to do

(15x15)+(10x10)= the slpoe.

Hope that helps.

Answer:the square root of 325.
