What is the value of x

71

Step-by-step explanation:

180 is a supplementary angle

x+36+73=180

36+73=109

x+109=180

180-109=71

So to make sure just add 36,71,73 together and you should get 180

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

hi! i think the answer is 1/2 : )
