To find the measures of angles ∠1 and ∠3, we can let each angle be represented as \( x \). Since ∠1 and ∠3 are vertical angles, they are equal. Therefore, we can set up the equation:
\[ 2x = 68° \]
So, the correct response that solves for the value of each angle is:
2x° = 68° 2 x equals 68 degrees.
From this equation, you can solve for \( x \).
