you are building a ramp that will be in the same shape of a perfect right angled triangle. the vertical height of the ramp will be 10 feet. the horizontal base of the ramp will be 15 feet. what will be the length of the downward sloping side of the ramp?
A 18feet
B 19feet
C 20feet
D 21 feet

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. 
You should do this on a calculator, by the way, because not a lot of people can do square roots in there head. lol

i don't get it

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.
