name the angle that is supplementary to <COB
To find the angle that is supplementary to <COB, you need to first understand the concept of supplementary angles. Supplementary angles are two angles that add up to 180 degrees. In other words, if angle A and angle B are supplementary, then angle A + angle B = 180 degrees.
In the given question, we have angle COB. To find the angle that is supplementary to <COB, we need to subtract angle COB from 180 degrees.
Let's assume that angle COB measures x degrees. Then, the angle that is supplementary to <COB can be found by calculating 180 - x degrees.
