Answer:
Supplementary
Explanation:
Both angles are consecutive interior angles. These are interior angles formed within the inner region of the two parallel lines. Therefore they are supplementary
Since the angles are supplementary, their sum is 180°
(2x - 23) + 147 = 180
so 2x - 23 = 33
therefore angle (2x - 23) = 33
Congruent angles are two or more angles that are identical to each other.
Since the angle (2x - 23) is 33°, and the other angle is 147°, they are not congruent (equal).
