Determine the Height Project Math 1060 Trigonometry Project Aaron Strader In the 1840's surveyors calculated the height of Mt. Everest.

Trigonometry is still used today when direct measurements or satellite surveys are not possible or appropriate.

Aiming the inclinometer so that I could see the very top of the object I measured an angle of 49 degrees. Using a trigonometric function, I found the height of the building minus my eye level. I then added my height to that number and found the buildings height to be 75ft.

In the 1840's surveyors calculated the height of Mt. Everest. Their calculations were within 0.1% of theheight determined by modern satellite surveys. The early surveyors used trigonometry to complete theircalculations. Trigonometry is still used today when direct measurements or satellite surveys are notpossible or appropriate.  In this project you will use trigonometry and right triangles to determine theheight of 2 objects on campus with two measurements that you can make on the ground

● Using heavy construction paper and a template that was provided I constructed an inclinometer.

● I found a building whose base I could approach.

● Standing at the base of the object I walked 60ft away.

● Aiming the inclinometer so that I could see the very top of the object I measured an angle of 49degrees.

● Using a trigonometric function, I found the height of the building minus my eye level. I thenadded my height to that number and found the buildings height to be 75ft.

● For the second structure, I choose an object whose base was not accessible but stillperpendicular to the ground, a gazebo in a nearby park.

● Standing at some point “P”, I measured the angle of inclination  to the top of the structure. Itwas 33 degrees.

● I then walked away from the object to some other point “Q” which was 20ft away from “P”.

● From point Q I measured the angle of inclination to the top of the structure. It was 21 degrees.

● Using my measurements and the correct trig relationship, I solved for the length of one side ofthe oblique triangle (figure 1). I found the length of the bottom right side to be 34.5ft. This sidewas the same side as the “P” triangle’s hypotenuse.

● Using my new found hypotenuse I used a similar equation from the first problem (figure 2) andfound the height of the structure minus eye level, it was 18.8ft. I then added the eye level heightand found the true building height to be 24.8ft.

● Reflective Writing

In the process of completing this project I have gained some valuable knowledge. I am a veryapplication driven person. This fact is one of the reasons that I am in math and find it sointeresting. It also makes other subjects much more difficult for me. It is hard to find application to17th century economics. Trigonometry and other math principles explain our world and help us todo things as incredible as going to the moon, or as simple as finding the height of a gazebo. I do alot of construction and can think of a lot of future applications for this procedure. last spring I hadto find the height of an electrical pole in my driveway. I had to run out to my fathers house, grab aladder and then send my soft body 30ft up into the sky to get an accurate reading on the height. Inthe future I will not have to brave an unstable ladder. I will grab my inclinometer. I will also makesure to use the correct equation. because failing to do so during this project cost me over a halfhour of extra work and thought. Time that could have been spent finding the heights of otherobjects in my area.
