6-15.

The angle of elevation of the sun (the angle the rays of sunlight make with the flat ground) at 10:00 a.m. is 29°. At that point, a tree’s shadow is 32 feet long. How tall is the tree?

Draw a diagram to represent the situation.

Right triangle labeled as follows: horizontal leg, 32 feet, vertical leg, x, angle opposite vertical leg, 29 degrees.

Use trigonometric relationships to solve.
