The acute angle AOB is 70 degrees. beam OC divides the angle AOB into two angles AOC = 42 degrees. find the angle of the COB and determine its type?
Because the angle AOC is 70 degrees, and the beam OS divides it into two angles AOC and AOC, then the angle AOC = AOB-AOC
COB = 70-42 = 28 degrees
28 degrees less than 90, therefore the angle of the COD is sharp
