Answer: x = 101, y = 20
From corresponding angles, as both pairs of lines are parallel, we know that 79 is the supplement of x. That means 79 + x = 180.
From this we have x = 101 degrees.
From corresponding angles, x is the supplement of ( 4y - 1 )
Since we know x = 101, we can plug it into our equation:
4y - 1 + 101 = 180
Simplifying:
4y + 100 = 180
Subtracting 100 from both sides of the equation:
4y = 80
Dividing by 4:
y = 20
Hope this helps!
