degrees.

x = 67 degrees

Step-by-step explanation:

180 = 46 + x + x

180 = 46 + 2x

180 - 46 = (46 - 46) + 2x

134 = 2x

134/2 = 2x/2

x = 67

x=67°

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
