Question

(a) What was the measure of the angle of elevation from his position to the peak?

(b) If he would have made his calculation from 80 kilometers closer to the peak, what would have been the measure of the angle of elevation?

Answer 1

hint...Your right angle triangle uses the tangent ratio (O/A).
b) hint... Your right angle triangle uses the tangent ratio where the adjacent is now 160 m
