16)

(4x + 2) is equal to 150 because they are vertical angles. When two lines intersect, on the opposite sides of the x like these are will be equal to one another. So let’s make them equal to each other.

4x + 2 = 150

Subtract 2

4x = 148

Divide by 4

x = 37

So it will be A

17)

The two angles added up with each other

34 + 146 = 180

Since these two add up to 180 degrees, they would be supplementary angles.

So, H

18)

The two angles will make a 90 degree angle (as shown with the little box formed in the corner)

When angles add up to make 90 degrees, they will be complimentary angles.

So, C.
