Answer:
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°
The answer is D-both A and C. Pi is irrational, but we know that when you multiply it with two you get 6.28... the number stops three places after the decimal in B. So it isn’t B or E. In C the number never reaches and end, so the answer would be D.
