Answer: tan 20 = 60/x
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
tan α = opposite side / adjacent side
Where α is the angle of elevation from point G on the ground to the top of a flagpole, the opposite side to the angle is 60, and the adjacent side is the distance from point G to the base of the flagpole (x).
Replacing with the values given:
tan 20 = 60/x
