2. Suppose the angle of depression from a race car driver's eyes to the bottom of the 3-foot high back end of the car in front of him is 18 degrees.

How far apart, to the nearest foot, are their bumpers? Assume the horizontal distance from the race car driver's eyes to the front of his car is 5 feet.

The bumpers are ? feet apart.

1 answer

3 feet / d = tan 18°
so
d = 3 feet / tan 18° = a little over 9 feet

Subtracting the 5 feet to the front of the driver's own car
leaves a distance between bumpers of 4 feet.
