Answer:
Angle DOC
Step-by-step explanation:
Since angle AOC and angle DOC are ajacent angles that form a straight line, they are supplementary to each other.
By the definition of supplementary angles, you can determine that angle AOC + angle DOC = 180.
Also notice that angle DOC is a right angle (90 degrees), so you can also determine that angle AOC is also a right angle since they are supplementary.
the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements
Total ratio = 4+7 = 11
33/11 = 3
4x3 = 12
7x3 = 21
so the two groups are 12:21
which is also = 4:7
