What is the value of x?

x=8

Step-by-step explanation:

you know that the total of all the angles should add up to 360 so if you add up all of the known numbers you get 264 and then subtract from 360 you get 96. So the angle measure is 96; 12x=96. Then you divide both sides by 12 to get x alone and you get x=8

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
