Question

An observer flying in an aeroplane at an altitude of 900m observes 2 ships in front of him, which are in the same direction at an angles of depression of 60 and 30 respectively. find the distance between the two ships

Answer 1

First take right angle with 60degees Tan 60=900/x Root3=900/x X=900/root 3 X=300root3 Next take 30 degree, Y=900root3 Y-x=600root3 so the distance between them is 600root3
