- Given the triangle above (not drawn to scale), with side lengths aaa, bbb, and ccc, select all items that give the measure of θ\thetaθ.
- Evaluate sin(30)\sin(30)sin(30), in degrees.
- Find x, in degrees: sin(x+30)=sin(x)\sin(x+30) = \sin (x)sin(x+30)=sin(x)
- Find x, in degrees: sin(x)=cos(x)\sin(x) = \cos(x)sin(x)=cos(x)
- Find x, in degrees: sin(x−15)=cos(x+15)\sin(x-15) = \cos(x+15)sin(x−15)=cos(x+15)
