Answer:

x = 25, y = 19

Step-by-step explanation:

The external angle is supplementary to the adjacent internal angle.

2x +130 = 180

2x = 50 . . . . . . . subtract 130

x = 25 . . . . . . . divide by 2

The external angle is equal to the sum of the remote internal angles.

130 = 54 +4y

76 = 4y . . . . . . . subtract 54

19 = y . . . . . . . divide by 4
