Correct Answer
Option A
Explanation
To solve the problem, we need to understand the relationship between the angles formed when two parallel lines are intersected by a transversal. The two interior angles on the same side of the transversal are supplementary, meaning their sum is 180°. Given angles: 1. \( (2x + 15°) \) 2. \( (3x - 20°) \) According to the property of supplementary angles: \[ (2x + 15°) + (3x - 20°)…Read More
