Answer:
the answer is non of these
Step-by-step explanation:
because when angle and the height is given and said to find the distance then we have to divide the height of the object by the given angle.
If we do like this
20/60 we get 0.33333333333
so the answer is none of these.

Answer:
angle of Depression = angle of elevation
60 = 60
we Know that tan = opposite / adjacent
therefore Tan 60 = √3
√3 = opposite / adjacent
√3 = 20/ adjacent
adjacent = 20/ √3
adjacent = 11.547= 11.55
answer b is the correct option
i hope it is helpful
