Question

I need help on this parallelograms question.

Answer 1

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

Answer 2

180-132+x-6x+12=0
48+x-6x+12=0
48-5x+12=0
60-5x=0
-5x=-60
x=12
