x 5 ft 8” 36.5 ft. The shadow was a length of 36.5 ft.(short leg) The angle was at 28 degrees PICTURE
Trigonometry Nhan and Freddy both used Trig to find the answer of the missing side: WORK: TAN (28) = X 36.5 X TAN (28) x 36.5 = X X = 19.4 28 36.5
LeiAloha used Strategy of Similarity: 5.8 X 15.5 36.5 = 211.7=X(15.5) 211.7/15.5=X 15.5 ft X X=13.658 5’8” 28 36.5 SIMILARITY
Marcus work: 30,60,90 angles theorem
Nhan and LeiAloha’s strategies were more accurate and they came out with closer measurements. Using Tan, the answer was 19.4.. Using Similarity, the answer was 13.658.. We preferred using Tan, because the results were easier to receive, and they were more accurate. Also, they came out the same rather than Marcus’s way was less accurate because he had less accurate answers and his answers were longer and he rounded 28 and 62 degrees to 30 and 60. Comparisons
