See the attached figure to better understand the problem
we know that
tan 29°=AC/CB--------> CB=AC/tan 29° AC=110 ft CB--------> <span>how far the man is from the helicopter landing pad </span>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
