Answer:
x = 28 degrees and y = 47 degrees
Step-by-step explanation:
The angles marked 40 degrees and 5x degrees sum to 180 ( adjacent angles), so:-
5x + 40 = 180
5x = 140
x = 28 degrees
The angles 5x and 3y -1 are exterior alternate angles so are equal in measure:-
5x = 3y - 1
140 = 3y - 1
3y = 141
y = 47 degrees
