A six-foot person walks from the base of a broadcasting tower directly toward the tip of the shadow cast by the tower. When the person is 132feet from the tower and 3feet from the tip of the shadow, the person's shadow starts to appear beyond the tower's shadow.
(a) Draw a right triangle that gives a visual representation of the problem. Label the known quantities of the triangle and use a variable to represent the height of the tower.
(b) Use a trigonometric function to write an equation involving the unknown quantity.
(c) What is the height of the tower?
