Solve the equation. then check your solution.
5/9d = 9/10

The equation is TRUE.

Step-by-step explanation:

To solve the given equation:

You need to find the value of the variable "d". You can apply this procedure:

- Multiply both sides of the equation by 9:

- Divide both sides of the equation by 5:

Check the solution substituting the value of "d" into the equation and evaluating:

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
