SOLUTION:
Co-interior angles on parallel lines must add up to 180°.
( 132 - x ) and ( 6x - 12 ) are co-interior angles.
Therefore:
( 132 - x ) + ( 6x - 12 ) = 180
132 - x + 6x - 12 = 180
- x + 6x = 180 - 132 + 12
5x = 60
x = 60 / 5
x = 12
FINAL ANSWER:
Therefore, the answer is:
x = 12
Hope this helps! :)
Have a lovely day! <3
