One airport has a ramp sloping down from the passenger waiting area to the plane. If the distance from the waiting area to the plane is 23 feet and the height from the ground to the waiting area is 5 feet, how long is the ramp?

Step-by-step explanation:

GIVEN: One airport has a ramp sloping down from the passenger waiting area to the plane. If the distance from the waiting area to the plane is and the height from the ground to the waiting area is .

TO FIND: length of ramp.

SOLUTION:

Consider the figure attached

Distance from the waiting area to the plane

height from the ground to the waiting area  

let the length of ramp be

Now,

Using Pythagorean theorem

Hence the length of ramp is

the line of

1. perpendicular

2. parallel

3. perpendicular
