My attempt- sin(x+30)=1/2 sin(angle)=1/2 shift sin 1/2=30 x+30=30 x=0 so x=0, 180, 360 this is a multiple choice question and the answers are-(A) 0,120 OR 360. (B) 0 OR 120 (C) 30 OR 150 (D) 120 OR 360 Thanks for any help in advanceAnswer by stanbon(57239)   (Show Source): You can put this solution on YOUR website!If sin(x+30)=1/2 (0≤x≤360), then x is equal to? ---- If sin(x+30) = 1/2, x+30 must be 30, or 150, or 390 ---- If x+30 = 30, x = 0 If x+30 = 150, x = 120 If x+30 = 390, x = 360 Ans: A --- Cheers, Stan H.
