B. 34

Bonus: x is 94.

Step-by-step explanation:

Looking at the picture, the 112-degree angle is supplementary (180 degrees total) to the 2y angle. As a result, we can form the equation: 112 + 2y = 180.

112 + 2y = 180

First, subtract 112 from both sides.

2y = 180 - 112

2y = 68

Then divide both sides by 2.

y = 68/2

y = 34

Bonus:

x + 18 is vertical to 112, so the equation x + 18 = 112 will be used.

x + 18 = 112

Simply subtract 18 from both sides.

x = 112 - 18

x = 94
