The rescue helicopter

The rescue helicopter is above the landing site at a height of 180m. The site of the rescue operation can be seen from here at a depth angle of 52° 40 '. How far will the helicopter land from the rescue site?

Correct answer:

x =  137 m

Step-by-step explanation:

y=180 m A=52+40/60=315852.6667   tanA=y:x  x=y/tanA=y/tan52.666666666667° =180/tan52.666666666667° =180/1.311105=137=137 m
