Question

Who will give the answer first I will mark as brainlist answer​

Answer 1

Answer:

x=90

y=60

Step-by-step explanation:

x=90 because it is parallelogram

y=60 because of alt.int.angles

Answer 2

x = 100°

y = 60°

z = 20°

These are your final answers...

$angle \: pqr = 180 - 80 \\ angle \: pqr = 100 \\ x = angle \: pqr = 100 \: \: \: (opp. \: angles \: of \: llgm \: are \: equal) \\ in \: triangle \: prs... \\ x + 60 + angle \: prs \: = 180 \: \: \: \: (by \: asp) \\ 100 + 60 + prs = 180 \\ 160 + prs = 180 \\ prs = 180 - 160 \\ prs = 20 \\ z = prs = 20 \: \: \: \: (alternate \: interior \: angles) \\ z + y = 80 \: \: \: \: (exterior \: angle \: property) \\ 20 + y = 80 \\ y = 80 - 20 \\ y = 60 \\ \\ hence \: we \: have... \\ x = 100 \\ y = 60 \\ z = 20$
