Question

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?

Answer 1

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

I did it and it was correct!

the answer is

the man is 198.45 ft from the helicopter landing pad

Answer 2

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
