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

-1   1/6.   you dont subtract the denominators

step-by-step explanation:

really your just stupid if you don't know this

step-by-step explanation:

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
