Answer:
∠5 = 53°
Explanation:
The two diagonal lines are parallel according to the triangle symbols, indicating parallelism.
We know that if two parallel lines are cut by a transversal, then their corresponding angles, alternate exterior angles, and alternate interior angles are congruent.
Angle 5 and the 53° angle are corresponding angles. Due to the Corresponding Angles Theorem, we know that ∠5 = 53°.
