Answer:
the first one
Step-by-step explanation:
y-y1=m(x-x1)
y-20=12(x-3)

simplify:

Answer:
11 + 12 = 23
Step-by-step explanation:
Answer:
∠ 1 = 20 x + 5
∠ 2 = 24 x - 1
If lines l and m are parallel:
∠ 1 + ∠ 2 = 180°
20 x + 5 + 24 x - 1 = 180
44 x + 4 = 180
44 x = 180 - 4
44 x = 176
x = 176 : 44
x = 4°
