Question

The distance from the bottom of a ramp to the back of a moving truck is 11 feet. If the angle between ramp and the ground is 21.3, how high is the back of the truck off the ground?

Answer 1

4.29 feet to the nearest hundredth.

Explanation:

tan 21,3 = h / 11 where h is the height of the back of the truck.

h = 11 tan 21.3

= 4.29 feet.
