Best ResponseYou've already chosen the best response.0sin theta = 1/2  1 = 1/2 first use your calculator to find the angle whose sine is 1/2 then you can find theta  recall that the sine is negative in the 3rd and 4th quadrants

Best ResponseYou've already chosen the best response.0but pi/6 is not the answer as the sine is negative 1/2 there are 2 solutions  one in 3rd and one in 4th quadrant
