23

Step-by-step explanation:

1 Simplify \frac{10}{1}

1

10

to 1010.

10=\frac{230}{x}10=

x

230

2 Multiply both sides by xx.

10x=23010x=230

3 Divide both sides by 1010.

x=\frac{230}{10}x=

10

230

4 Simplify \frac{230}{10}

10

230

to 2323.

x=23x=23

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
