1. 62 and (4x+2) are alternating interior angles and they are equal
so
62 = 4x+2 now solve for x
2. vertical angles are straight across from each other
1 and 4
2 and 3
5 and 8
7 and 6
Alternate interior : alternate (or cross) the Transversal and are interior (inside) and are equal
4 and 5, 3 and 6
Corresponding are the angles in matching corners
1 and 5, 2 and 6, 3 and 7, 4 and 8
Alternate exterior : alternate (or cross) the Transversal and are exterior (outside)
2 and 7, 1 and 8,
