Slope- intercept equation from graph.

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

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
