Answer:
x = 96°
y = 102°
Step-by-step explanation:
Angles on a straight line add up to 180
78 + y = 180
y = 180 - 78
y = 102
Angles in a quadrilateral add up to 360
78 + 90 + x + x = 360
78 + 90 + 2x = 360
168 + 2x = 360
2x = 360 - 168
2x = 192
x = 192/2
1/3 or 0.33

LMK if it does and weather it is wrong or right
x intercept = -1, 3 and 4
y intercept = 12
30°
180-75-75=30
