To find the measures of the angles ∠1 and ∠3, which are vertical angles, we know that vertical angles are equal. Given that the sum of their measures is 68°, we can set up the equation as follows:
Let x be the measure of each angle. Since ∠1 and ∠3 are equal, the equation would be:
\( x + x = 68° \)
This simplifies to:
\( 2x = 68° \)
So, the equation that solves for the value of each angle is:
2x° = 68°
This option reflects that the two angles are equal and together equal 68°.
