Average Height: During this project, our group learned that math can be used daily and is all around us. We used trigonometry and special right triangles to figure out the height of the light pole in the courtyard. We used a clinometer to figure out the angle(s) of the triangle. After we found the angle measusurements of the triangle, we were able to calculate a portion of the light pole. To find the other half of the light pole, we added our height from our eyes to the portion of the pole we already figured out. Once we added these two measurements together, it gave us the total height of the light pole. Conclusion
