Answer to Question #300058 in Trigonometry for Ravneet

Question

A cadet rappelling down a cliff on a rope needs help. A cadet on the ground pulls tight on the end of the rope that hangs down from the rappelling cadet to lock the cadet in place. The length of the rope between the two cadets is 129 feet, and the angle of elevation of the rope is 75°. How high above the ground is the cadet on the rope? (Round your answer to two decimal places.)

Answer 1

$Sin75°=\frac{h}{129}$

$h =129sin75°$ =124.6ft
