i dont get why the answer for 5.a. says that theta can be either 75 degrees or 117 degrees when the question specified that the angle is acute? i understand the ASTC rule which is: since sine is positive it can either be A (the angle itself) or S 180 - the angle
but i dont understand how the S is applicable here since the question said that theta is actue
is this a typo?
