MArishka [77]

Answer:

  • x = 80°
  • y = 130°

Step-by-step explanation:

The interior is a parallelogram when adjacent angles are supplementary. This requires ...

  (x -30)° + (x +50)° = 180°

  2x + 20 = 180 . . . . . . . . . . . collect terms, divide by °

  2x = 160 . . . . . . . . . . . . . . . subtract 20

  x = 80 . . . . . . . . . . . . . . . . . divide by 2

Then the angle x+50 is ...

  (x +50)° = (80 +50)° = 130°

This is also the measure of the angle marked y.

For the lines to be parallel, x = 80, y = 130°.
