Answer:
x = 80
Step-by-step explanation:
x + 30 = 110 (Opposite angles are equal)
x = 110 - 30
x = 80
Answer:
X=55°
Y=30°
Step-by-step explanation:
2y=x+5
Y=1/2x+2.5
3y+30=4x-100
3(0.5x+2.5)+30=4x-100
1.5x+7.5+30=4x-100
4x-1.5x=137.5
2.5x=137.5
X=55°
Y=30°
The point-slope form:

We have the point (8, -4) and the slope m = -56. Substitute:
