$\sin(\theta)=0.25$ $\theta=\arcsin\left(0.25\right)$ [asin] [ ( ] [0] [.] [2] [5] [ ) ] [ = ]

Think of it as a measurement of a triangle, you can go both the minus way and the positive way it doesn't matter. So if you get the angle 14.5 degrees there also the angle -14.5 which can be expressed as 180-14.5 = 165.5
