Answer:
164.85 m
Step-by-step explanation:
You have a right triangle with 60 as the side opposite the 20° angle and you are looking for the adjacent side to that angle.
The trig function to use is the tangent of an angle = opp/adj
Let x = distance from you to the base of plateau
So, tan 20 = 60/x
x tan 20 = 60
x = 60/tan 20
x = 164.85 m
You must memorize the definitions all of the trig functions so you can do a problem like this one. OK?
