FINDING THE  SIN, COSINE, AND TANGENT #1-KEY

Directions:  Find the sin, cosine, and tangent of the given angles below                 1)  cos C =   12/13                                                                   2)  cos C =   8/10 = 4/5 sin C =   5/12                                                                           sin C =   6/10 = 3/5

tan C =   5/12                                                                          tan C =   6/8 = 3/4             3)  cos C =   24/25                                                                   4)  cos C =   48/50 = 24/25 sin C =   7/25                                                                           sin C =   14/50 = 7/25

tan C =   7/24                                                                          tan C =   14/48 = 7/24            5)  cos C =   24/26 = 12/13                                                     6)  cos C =   12/15 = 4/5

sin C =   10/26 = 5/13                                                             sin C =   9/15 = 3/5  tan C =   10/24 = 5/12                                                             tan C =   9/12 = 3/4       www.imathworksheets.com
