Answer 1

By definition, Vertical angles are those angles opposite each other that share a common vertex. These angles are congruent, which means that they have equal measure.

You can see in the picture that two lines intersect each other and several angles are formed.

Based on the explained above, you can identify that the angle 1 and the angle 3 are Vertical angles. Then:

`m\angle1=m\angle3`

Therefore, knowing that the measure of the angle 1 is:

`m\angle1=120\degree`

You can determine that the measure of the angle 3 is the shown below:

`m\angle3=120\degree`

The answer is:

`m\angle3=120\degree`
