Homework Answers
Draw a picture of the situation. The height of the girl is the
upright leg of a right triangle. The ray of light from the sun
touching the top of her head is the hypotenuse and goes down and
away from her at a 25° angle to the horizontal. Basic trig will
show that
H/Ls = tan25° or
Ls = H/tan25° = 5/tan25° = 10.72 ft
