Brainliest for the best answer, ! find the value of x

x = 7

Step-by-step explanation:

Note that the line of length 2x - 6 is a mid- line segment as it bisects the 2 sides of the triangle. Accordingly it is half the length of the third side, that is

2x - 6 = 8 ( add 6 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

answer: it's a

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
