Answer 2

The measure of ∠s is 80°

Given:

∠r and ∠s are vertically opposite angles and ∠r = 80°

To Find:

∠s

Solution:

Vertically opposite angles are the angles that are opposite to each other at a particular vertex.

Vertically opposite angles are always equal.

Given that, ∠s and ∠r are vertically opposite angles.

∴ ∠r = ∠s

⇒ ∠r = ∠s = 80°

Therefore, the measure of ∠s is 80°
