# Thread: Angles of Elevation and Depression Help!

1. ## Angles of Elevation and Depression Help!

I am having problems with some questions:

A student can see a water tower from the closest point of the soccer field at San Lobos High School. The edge of the soccer field is about 110 feet from the water tower and the water tower stands at a height of 32.5 feet. What is the angle of elevation if the eye level of the student viewing the tower from the edge of the soccer field is 6 feet above the ground? Round answers to the nearest tenth degree.

and

The town of Belmont restricts the height of flagpoles to 25 feet on any property. Lindsay wants to determine whether her school is in compliance with the regulation. Her eye level is 5.5 feet from the ground and she stands 36 feet from the flagpole. If the angle of elevation is about 25 degrees, what is the height of the flagpole to the nearest tenth foot?

1. Draw a sketch.

2. You are dealing with a right triangle. Use the tan-function:

$\tan(25^\circ) = \frac x{36}$

3. Solve for x. x must be smaller or equal 19.5 feet.
