Answer :
1)
In fig. PQ || BC
And AC,AB are transversals...
therefore,
1) Angle ACB = y
Angle QAC = Angle ACB... Alternate Angles
But Angle QAC = 80⁰
that's why Angle ACB = 80⁰
y = 80⁰
2) Angle ABC = x
Angle PAB = Angle ABC... Alternate Angles
But Angle PAB = 30⁰
that's why Angle ACB = 30⁰
x = 30⁰
3)
<PAB + <QAB = 180⁰..angle in linear pair
30⁰ + ( z + 80⁰ ) = 180⁰
30⁰ + z + 80⁰ = 180⁰
110⁰ + z = 180⁰
z = 180⁰ - 110⁰
z = 70⁰
