30 degree triangle 30,60, 90 triangle hyp.= 2*Short leg Long leg= short leg*sq. root of 3 My height=5.42ft Distance to pole= 38 feet Height of triangle= 38/ square root of 3= 38 square Root of 3 over 3. Height of pole= sq. root of 3 over Trigonometry: tan of 30= x/38 Tan (30) 38= Height of triangle= Height of pole= Height of pole= 27.36

45 degree triangle In 45,45,90 triangle leg=leg and hyp=leg x square root of 2. 24ft + my height =the height of the pole. My height = 5.33ft Height of pole= 29.33ft Trig. Tan=opp/adj Tan45=x/24 X=24 Height of pole= 29.33ft 24ft

60 degree triangle In a 30,60, 90 triangle hyp.= short leg(2) and the long leg= short leg (square roots of 3) My height=4.66ft 14ft X Special right triangle Long leg= 14 (square root of 3) therefore… The height of the pole is 14 square roots of 3 Trigonometry Tan= opp./adj. Tan 60=x/14→ X= Tan 60 X 14 → 24.25

50 degree triangle 20 Trigonometry: Tan = opp./adj. Tan50 = X/20 X = My height = 6ft Height of pole = x

In Conclusion… Average height of the pole: =110.77/4= During this process we used the clinometers to measure our angle measures to the pole, then calculated our distance in feet. After that we applied special right triangle math and trigonometry to determine the height of the pole.
