Answer» Answer: 90 Step-by-step explanation: hello mate it could be 1/ 2 in both cases as values of sin and cos LIES between -1 and 1. cos (theta) = 1/2 is given the value of cos is 1/2 when the ANGLE is 60 so theta will be 60 given sin (PHI) = 1/2 value of sin is 1/2 when angle is 30 since sin 30 = 1/2 so phi is 30 so totally he has asked to find theta + phi which is equal to 60 + 30 that is 90 hope it HELPS you mark me brainliest if you like my explanation and answer |
