SOLUTION: A police helicopter flying at a height of 85 feet shines a light on a speeding vehicle below. If the angle of depression is 62 degrees, how far away to the nearest foot is the car

Question 827663: A police helicopter flying at a height of 85 feet shines a light on a speeding vehicle below. If the angle of depression is 62 degrees, how far away to the nearest foot is the car?
Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
we have a right triangle and to get the internal angle of the right triangle formed at the helicopter we subtract 62 degrees from 90 which equals 28 degrees
we now use the cosine to find the distance (d) from the helicopter
cosine 28 = 85/d
d = 85 / cosine 28 = 85 / 0.8829 = 96.2736 = 96 feet
