A helicopter is hovering 110 feet in the air over a landing pad. If a man sees the helecopter at an angle of elevation of 29°, which of the following shows how far the man is from the helicopter landing pad?
see the attached figure to better understand the problem
we know that
tan 29°=AC/CB--------> CB=AC/tan 29° AC=110 ft CB--------> how far the man is from the helicopter landing pad so CB=AC/tan 29°----------> CB=110/ tan 29°----------> CB=198.45 ft
the answer is the man is 198.45 ft from the helicopter landing pad
