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
