ans this....hope u can solve this​

Answer 1

Heya,

Here is your answer mate...

It is given in the question that PQ ll ST

Angle pqr = 110°

And angle RST = 130 °

Angle pqr + angle qrx = 180 (angle on the same side of transversal)

=> 110 + angle qrx = 180°

=> angle QRX = 180 - 110

= 70°

And,

∠RST + ∠SRY = 180° (Angles on the same side of transversal)

130° + ∠SRY = 180 °

∠SRY = 180 - 130

= ∠SRY = 50

Now,

∠QRX + ∠SRY + ∠QRS = 180o ( Angle made on a straight line)

70o + 50o + ∠60 =180

Hence it is parallel
