Question

please mates, answer the pic​

Answer 1

Answer:

S+R= 180 ( PS is parallel to QR so P ,Q are alternate interior angle)

Angle R would be 90°

and angle P = 50°

Answer 2

Answer:

since PS is parallel to QR

 angle SPQ = 180 - 130

                   = 50 degree (answer)

 angle SRQ = 180-90

                   =90 degree (answer)
