A tower casts a shadow 11 feet long. The distance from the top of the tower to the end of the shadow is 61 feet. how many feet tall is the tower?

61Squared = 11squared = h squared
3721 = 121 + h squared
-121 = -121
3600 = h squared
I get stuck at this point. Please help!

I think you then have to take the square root of 3600 to solve for just h and you would get 60ft.
I just need help I don't even know where to begin
