Answer:
x = 18
Step-by-step explanation:
When two parallel lines are intersected by a transversal, then same-side exterior angles are supplementary, meaning their angle measures add up 180 degrees. Applying this knowledge here, one can state that;
( 6x - 3 ) + 75 = 180
Simplify,
6x - 3 + 75 = 180
6x + 72 = 180
Inverse operations,
6x + 72 = 180
-72 -72
6x = 108
/6 /6
x = 18
