Answer :
Answer:
80 and 100
Step-by-step explanation:
Suppose line AB and CD are parallel to each other, and lint GH intersect both at point L and M.
Now for same side interior angles of parallel lines, we know that
"sum of same side interior angles is 180° or they are supplementary angles"
Now, ∠DML + ∠BLM = 180°
∠M = x
∠L = y
Since, one angle is 20° less than second,
y=x-20
So we can make an equation,
x + y =180
x+x-20=180
2x-20 = 180
2x = 180-20
2x = 160
x = 160/2
x = 80
Hence, y = 100
