Check your Understanding A. Lines p and q are cut by a transversal, find the value of x that makes p ∥ q.
1. ∠4 and ∠5 are alternate interior angles, m∠4 = 5x − 11 and m ∠5 = 3x + 7.
2. ∠4 and ∠6 are same side interior angles, m∠4 = 6x +3 and m ∠6 = 4x + 7.
3. ∠2 and ∠6 are corresponding angles, m∠2 = 3x − 15 and m ∠6 = x + 55.
