Step-by-step explanation:

A. 145 degrees

Step-by-step explanation:

If you think about it 1 and 3 are the same thing. Since 4 is 55 degrees. We can subtract 55 from 90 which would be 35 degrees. So we simply because, 1 would 35 degrees. We subtract 35 from 180. Which would be 145 degrees.

Therefore, your answer would be A. 145 degrees

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
