Answer:

(x, y) = (18, 5)

Explanation:

Assuming the three lines meet at a single point at lower left (the figure is sloppily drawn), the angle (3x)°+49° is a corresponding angle to (7x-23)°. That means they have the same measure:

3x +49 = 7x -23

72 = 4x . . . . . . . . . add 23-3x

18 = x . . . . . . . . . . . divide by 4

__

Angles (3x)° and (11y-1)° are "corresponding" angles, so are congruent.

3x = 11y -1

3(18) +1 = 11y . . . . add 1, fill in the value of x

55/11 = y = 5 . . . . divide by 11

The values of x and y are 18 and 5, respectively.
