Question

The ramp on the back of a U-Haul truck is 11 feet long. If the back of the truck is 4 feet off the ground, what is the angle formed by the ramp in the ground

Answer 1

The angle between the ramp & ground is = 68.67 °

Explanation:

AC = length of the ramp = 11 ft

BC = 4 ft

From the ΔABC

`\cos \theta = (BC)/(AC)`

`\cos \theta = (4)/(11)`

`\theta =` 68.67 °

Therefore the angle between the ramp & ground is = 68.67 °
