Answer 2

The picture was a condensed from my notes, but I don't know how to do it.
the actual problem was along the lines of:
Bobby Teenager is walking away from a lamp post... the rate at which his shadow is changing is 1/3 the rate he is walking... the lamp post is 20ft high...
a) Explain how Bobby Teenager is 5ft tall.
b) Find the rate at which (theta) is changing when Bobby Teenager is 12ft away from the lamp post. and he is walking at a speed of 5 ft/min.
