Suppose a person begins walking away from a light pole at a constant rate of 0.88 meters per second. The person knows that as they walk away
from the pole that the length of their shadow increases. The person is wondering if the length of their shadow is also changing at a constant rate.
Assume that 0 is measured in degrees. The light pole is still 2.26 meters tall, and the person is still 1.37 meters tall.
