Question

A ramp extends from the back of a truck bed to the ground. The back of the truck bed is 3 ft above the ground. The horizontal distance from the spot below the back of the truck bed to the bottom of the ramp is 8 ft.

How long is the ramp?

Answer 1

Use pythagoras' theorem. So,
3^2 + 8^2 = 9 + 64 = 73
So the ramp is equal to the square root of 73.
Hope this helps!
