Answer:
4.44
Step-by-step explanation:
the real answer is 4.44444444444
Step-by-step explanation:
first one
when x=0, y=4
wheb x=4, y=0
y + (2x -12) = 180 (since they are supplementary angles)
(2x-12) = 96 ( since they are alternate exterior angle)
2x = 96 + 12
2x = 108
x = 108/2
x = 54.
y+( 2x-12)=180
y+(2× 54 -12) = 180
y + (108-12) = 180
y + 96 = 180
y= 180-96
y = 84.
