two intersecting lines create four angle; ∠1 and ∠3 are a vertical pair. Their sum of their measures is equal to 68o. What equation solves for the value of each angle?

Since ∠1 and ∠3 are a vertical pair, they are congruent. Let's call the measure of these angles x.

Since the sum of the measures of ∠1 and ∠3 is 68o, we can write the equation:

x + x = 68

This equation can be simplified to:

2x = 68

Dividing both sides of the equation by 2, we get:

x = 34

Therefore, the measure of each angle, ∠1 and ∠3, is 34o.
