Answer:
x = 11°
Step-by-step explanation:
Because of Alternate Exterior Angles, 5x - 12 = 43. Now, let's solve.
=> 5x - 12 = 43
=> 5x = 55
=> x = 11°
Hoped this helped.
x = 11
Alternate exterior angles are congruent where a transversal crosses parallel lines. That means ...
(5x -12)° = 43°
5x = 55 . . . . . . . divide by °, add 12
x = 11 . . . . . . . . . divide by 5
