Answer:
135°(b)
Step-by-step explanation:
x=85°(Alternate interior angles)
y=180°-130°(Linear pair)
=50°
x+y=85°+50°=135°
135°
In given figure, PQ parallel to ST and segment SO is a transversal.
∴x=85
[ Alternate interior angles ]
Here, PO is a straight line.
∴∠PQR+∠ROQ=180
[ Linear pair ]
⇒130
+y=180
⇒y=180
−30
⇒y=50
∴x+y=85
+50
⇒x+y=135
