Let’s do some… Example 1:
A = 40º, b = 3 and c = 2
3
Example 2: a = 8, b = 9, c = 7
4
Okay, let’s mix it up! Solve for the missing values in each triangle.
a = 38, b = 25 and C = 90º A = 75º, B = 50º and a = 7 A = 145º, a = 5, b = 10
5
Answers: A = 56.7º, B = 33.3º and c = 45.5 C = 55º, b = 5.6 and c = 5.9 None
6
Okay, now something interesting… Find the area of THIS!
B C 75º 124.5º 82.5º 201.5 ft 125 ft ft 158 ft 202 ft E D 97º 161º
7
Answer: 46,471.6 sq ft A B C 75º 124.5º 82.5º 201.5 ft 125 ft
D 97º 161º
