Suppose θ is an angle in standard position And cos θ=-1/2 and sinθ=-square root of 3 over 2. Can the value of θ be 60 degrees? Can it be -120 degrees ?

Find the exact value of: sin(7pi/6 + 3pi/4)
A.0 B.2 C.1 D.Infinity I need a step by step on how to do this.
I'm still new and confused with sin graphs. I know the answer is 4pi/9, 5pi/9, 10pi/9, 11pi/9, 16pi/9, 17pi/9 but unsure of how the denominator got to be 9. thank you!
