Correct Option: and are the same size

Step-by-step explanation:

Two angles are adjacent when they have a common side, a common vertex, and don't overlap.

The image shows the following angles are adjacent:

YVZ and YVX

YVZ and YVW

YVX and XVW

Furthermore, two angles are said to be linear if they are adjacent angles formed by two intersecting lines.

The first, fourth, and fifth options are true as shown above, which discards as true the second option.

The only probable false option is that XVW and YVX are the same size. They certainly could be, but we have to evidence of that, thus this option is considered false.

Correct Option: and are the same size

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

answer: its the third option.
