FINDING THE
SIN, COSINE, AND TANGENT #2-KEY
Directions: Find the sin, cosine, and tangent of the given angles below
1) cos C = 20/25 = 4/5 2) cos C = 16/20 = 4/5
sin C = 15/25 = 3/5 sin C = 12/20 = 3/5
tan C = 10/24 = 5/12 tan C = 10/24 = 5/12
3) cos B = 14/50 = 7/25 4) cos B = 7/25
sin B = 48/50 = 24/25 sin B = 24/25
tan B = 48/14 = 24/7 tan B = 24/7
5) cos C = 24/30 = 4/5 6) cos B = 9/15 = 3/5
sin B = 24/30 = 4/5 sin C = 9/15 = 3/5
tan C = 18/24 = 3/4 tan B = 12/9 = 4/3
