Answer» Answer: A+B = 90° Explanation: Given i ) sinA = \frac{1}{2} \IMPLIES SinA = sin30 Now , A = 30° ----(1) II ) cosB = \frac{1}{2} \implies cosB = Cos60 => B = 60° ----(2) Now, Value of (A+B) = 30°+60° [ from (1)&(2) ] = 90° Therefore,. A+B = 90° HOPE IT HELPS YOU please say thanks and MARK as BRAINLIEST |
