What is the measure of

First, you need to find the size of angle YXZ, which you can do because angles on a straight line add to make 180°.

180°-150°= 30°

Angles in a triangle also add up to make 180°.

You now have two angles, meaning you can find the remaining angle.

180°-(30°+65°) = 180°-95° = 85°

Angles on a straight line still add up to 180° so now you can find XZW.

180°-85° is going to give 95°, which means we could have skipped a step here, but that should only be done once an understanding of why is formed.

So the answer is A. XZW = 95°
