Question 6
Two cars (A and B) leave an intersection at the same time (from O), each on a different straight road
The angle between the roads is 12°. One car travels 90 km/h and the other travels at 120 km/h. After
minutes, a police helicopter hovering 1.0 km above a line on the ground connecting the two cars, notes
the angle of depression to the slower car is 14°. What is the horizontal distance (i.e., distance along the
ground, x) from the helicopter to the faster car? Answer to the nearest kilometre. Excuse the poor
drawing :)
