Question

With full explanation plz​

Answer 1

Answer:

y = 180-130 = 50° (Linear pair)

x = S (Alternate angles)

x = 85°

hence x + y = 130°+85°= 215°

Answer 2

PQO = OQR+PQR (Supplementary angles = 180)

180 = y+130

180-130 = y

50 = y

Since, ST II PO (ST and PO are parallel)

Thus, TSO = POS = x = 85 (Alternate angles)

= x+y

= 85 + 50

= ANSWER =  135
