130

Answer 2

Answer:

210

Step-by-step explanation:

Join BD

A five sided polygon will be formed

Sum of all angles in a five sided polygon is 180×(5-2)=180×3=540

Therefore as AB parallel to CD

Therefore angle ABD+ angle CDB=180(interior angles property in parallel lines)

Therefore

Angle OCD=540-(BOA+ABD+DBA+AOC)

=540-(130+180+20)

=540-330

=210
