  6. Conclusions • The average height of the foul pole for this project was 13.17 feet tall. • To find the height of the foul pole, each member of the group counted the distance from the foul pole at 10⁰, 30⁰, 45⁰, and 60⁰. We then used trigonometry and special right triangles to find the height of the foul pole. We used the distance from the base as one of the legs. For the special right triangles, we used a clinometer to measure the degrees in order to use the equation of tangent, and find the height. • One lesson we learned from this project is that the shorter the distance from the base, the greater the angle degree is.
