Answer:
C
Step-by-step explanation:
2x + 1 = 85 (Alternate Interior Angles Theorem)
2x = 84
<em>x = 42</em>
(3y + 5) + (2x + 1) = 180 (Linear Pair Theorem)
3y + 5 + (85) = 180
3y + 5 = 95
3y = 90
<em>y = 30</em>
Three times the square of a number means 
Nine times a number is 
If these quantities must be equal, we have
We can divide both sides by 3 to get
Since x is non-zero, we can divide both sides by x:
