Answer:
x = 147 degrees.
Step-by-step explanation:
The 2 horizontal lines are parallel.
The theorem says that 'for a line crossing 2 parallel lines alternate angles are congruent' so the angles marked are both 33 degrees.
These are sometimes called 'Z' because they are 2 angles inside the letter Z.
Also for a line crossing 2 parallel lines the 2 interior angles are supplementary (add up to 180 degrees) so:
x + 33 = 180
x = 180 - 33
x = 147 degrees.
