Angle α and β are supplementary angles and when added together equal 180.
Set up an equation:
α + β = 180
β = α +30
Replace β in the first equation, to get:
α + α +30 = 180
Simplify:
2α +30 = 180
Subtract 30 from both sides:
2α = 150
Divide both sides by 2:
α = 150 /2
α = 75 degrees.
I would think its D, but not totally sure
Y= x+1
y-3 = (-2-3)/(-3-2) (x-2)
y-3 = 1 (x-2)
y = x-2+3
y=x+1
