Answer 1

^ qrs= 130 corresponding angles are equal

Answer 2

Step-by-step explanation:

Draw a line XY parallel to PQ and ST

Now, PQ and XY are parallel and QR is transversal

angle PQR + angle QRX = 180 [ sum of the angle on the same side of transversal is 180]

110 + angle QRX = 180

angle QRX = 180 - 110

angle QRX = 70

Similarly, ST is parallel to XY

STR + SRY = 180 [ sum of the angle on the same side of transversal is 180]

130 + SRY = 180

SRY = 180 - 130

SRY = 50

QRX + QRS + SRY = 180 [ ANGLE ON STRAIGHT LINE]

70 + QRS + 50 = 180

QRS = 180 - 120

QRS = 60
