If angle ABC is 20 degrees and Reema wants to decorate some parts of the circular tablecloth with two different design papers, we can deduce that angle AOC will be 360 degrees minus the sum of angle ABC and angle BOC.

Given that angle ABC is 20 degrees, we need to find angle BOC to calculate angle AOC. Since the sum of the angles in a triangle is 180 degrees, we can determine that angle BOC is 180 degrees minus the sum of angle ABC and angle ACB.

Assuming angle ACB is also 20 degrees (as it is not specified), we can substitute the values:

Angle BOC = 180 - (20 + 20) = 140 degrees

Now, we can find angle AOC:

Angle AOC = 360 - (20 + 140) = 200 degrees

Therefore, angle AOC will be 200 degrees.
