Question

The ramp shown below is used to load heavy items into a moving van.

What is the measure of angle x?

Answer 1

x = 18 degrees

Explanation:

We are given 72 degrees. The box on the bottom left of the ramp is at a 90 degree angle. Given that this triangle will add up to 180 degrees no matter what we add the two given degrees; 72 + 90 = 162. Now we subtract; 180 - 162 = 18 degrees.
