Question

Dorothy made a skateboard ramp that is 4 feet high and has a base 16 feet long. The angle of elevation of the ramp is approximately (blank)°.

A. 3
B. 14
C. 20
D. 25

Answer 1

B) 14, it is the arctan(4/16)

Answer 2

For this case what you must do is find the tangent of the formed angle. We have then:
Tanx = (4) / (16) = 0.25
Clearing x we have
x = ATAN (0.25)
x = 14
answer:
The angle of the ramp is 14 degrees.
