2. The Clinometer This device is used to find the angle at which you are looking at an object. You solve the problems generated by using sine, cosine, and tangent properties. Some suggestions for improvement are: a more accurate way to “lock” the angle when it is measured. utilizing a better site to view through.

3. What I Am Trying to Find I am trying to find the height of this flag pole using the clinometer.

4. Method/Steps First you measure how far away you are standing from the object. I used a standard tape measure to measure my distance from the flag pole. It was fifteen feet. Then you find out how high you are off of the ground. I measured that my line of sight was six feet above the ground.

5. Method/Steps Now you use the clinometer to measure the angle to the top of the object.

6. Method/Steps The angle to the top of the flag pole was 39˚.

7. Setting Up the Equation

8. Finding the Answer

9. Answer & Discussion The flag pole was 18.1 feet tall. The actual height of the flag pole as purchased was 20 feet. The error in my answer and the actual height could be accounted to measurement error. The error in measuring both the angle and the distance where I was standing. Additionally, the difference in the answers could be due to the fact that the flag pole was not straight. The pole could have had a bend/tilt to it due to the wind pulling the pole in line of the direction of my vantage point.
