-50 = x/3+20 I NEEDDD HELOO

Given:

The equation is

To find:

The solution of the given equation.

Solution:

We have,

Subtracting both sides by 20, we get

Multiply both sides by 3.

Therefore, the solution of the given equation is .

i pretty sure it is

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
