Look at the figure. Find the value of x

x = 12

Step-by-step explanation:

Line JL is an angle bisector. This makes Line KJ and Link JM equal to each other.

2x - 7 = x + 5

x - 7 = 5

x = 12

Let's check to see if that works:

2(12) - 7 = 12 + 5

24 - 7 = 17

17 = 17

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
