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

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.

Answer 2

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