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            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
