Vertical angles are the same measurement and are opposite each other.

Angle 3 is opposite angle 1 and would also be 130 degrees.

Answer:

∠3

Step-by-step explanation:

See attachment.

As we can see, ∠1 and ∠3 lie opposite each other, while ∠2 and ∠4 lie opposite each other. In other words, ∠1 and ∠3 are vertical angles; by definition, then, ∠1 = ∠3.

We already know that ∠1 = 130°, so that must mean ∠3 also equals 130°.

The answer is thus ∠3.
