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

1 answer

If ∠1 and ∠3 are a vertical pair, it means that they are opposite each other and are congruent (have the same measure).

Let's assume that the measure of ∠1 is x degrees. Therefore, the measure of ∠3 is also x degrees.

The sum of the measures of ∠1 and ∠3 is given by the equation:

x + x = 68°

Simplifying the equation, we get:

2x = 68°

To solve for the value of x, we divide both sides of the equation by 2:

x = 68° / 2 = 34°

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