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 point)
2x = 68
68x2
<
268 = 180°
= 68
Let's assign variables to the unknown angles. Let's call angle 1 "x" and angle 3 "y". Since angles 1 and 3 are vertical angles, we know that they are congruent.
The sum of the measures of angles 1 and 3 is equal to 68°. So we can set up the equation:
x + y = 68
This equation represents the sum of the measures of angles 1 and 3.
