Final answer:
When two lines are parallel and intersected by a transversal, the corresponding angles are congruent. Angle 3 is corresponding to angle 1, so angle 3 measures the same as angle 1. Therefore, the measure of angle 3 is approximately 29°.
Step-by-step explanation:
When two lines are parallel and intersected by a transversal, the corresponding angles are congruent. Angle 3 is corresponding to angle 1, so angle 3 measures the same as angle 1.
Based on the given information, we can conclude that angle 1 measures approximately 29°.
Therefore, the measure of angle 3 is also approximately 29°.
