Question

From a balloon 1191 feet high, the angle of depression to the ranger headquarters is 72°54'. How far is the headquarters from a point on the ground directly below the balloon (to the nearest foot)?

Answer 1

tan(theta) = opposite/adjacent, solve for the opposite

you'll probably have to convert from minutes to degrees, just a moment

Answer 2

72°54'

1' is (1/60) of a degree

so 72°54' = 72 + (54/60) degrees [this is not your final answer this is just the first step]
