The angle measures of a hexagon add up to 720°. What is the measure of angle Z?

m∠Z = 166°

Step-by-step explanation:

Since we know that the angles add up to 720°, we can set up an equation to solve for the variable x:

12x + 14x - 6 + 108 + 108 + 108 + 90 = 720

26x + 408 = 720

26x = 312

x = 12

Now we substitute the number in for x to solve ∠Z:

m∠Z = 14(12) - 2 = 166

m∠Z = 166°

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
