Answer:
1) one angle is 100 and another angle is 80
2) one angle is 135 another one is 45
Step-by-step explanation:
1) angles on side of transversal their sum is equal to 180
as given their difference is 20
x+y = 180
x-y = 20
2y=160
y = 80
x= 100
2) the angles making linear pair so their sum is 180
let one angle be a
then
a + a/3 = 180
3a + a / 3= 180
4a/3=180
a= 135
and another be b
the b = 45
3) the diagram is tiny sorry
until is . is correct if correct then vote
