s = 60 ( Corresponding angles are equal)
r = 180 - 90 - s = 90 - 60 = 30
s - 2r = 60 - 60 = 0

Hence, OA is (A).

Since the lines l and m are parallel
\(s=60; \\
s+r+90 = 180; \\
r = 30\)

\(s-2r = 0\)
Option A

IMO A

In triangle ABC, t=50 (alternate angles for two parallel lines)
u+t+ 60=180
=>u=70

Also u+ 50+s =180 (straight line)
s=60
In traingle CDE: s+r+90 =180
=> r = 30

To find: s-2r = 60 - 2*30 =0
