Question

PLEASE HELP

A two feet tall wheelchair ramp is placed from a sidewalk to the main door of a library. If the length of the ramp is 16 feet, how far away is the bottom of the ramp from the sidewalk?

Answer 1

Distance from bottom to side walk = 15.87 feet (Approx.)

Explanation:

Given:

Height of ramp = 2 feet

Length of ramp = 16 feet

Find:

Distance from bottom to side walk

Computation:

Height of ramp (perpendicular) = 2 feet

Length of ramp (hypotenuse) = 16 feet

Distance from bottom to side walk (Base)

Base = √hypotenuse²- perpendicular²

Base = √16²- 2²

Base = √256 - 4

Base = √252

Base = 15.874

Distance from bottom to side walk = 15.87 feet (Approx.)
