Answer:

i found this ....Theorem:

Angle OBA = Angle BAO = b° And, using Angles of a Triangle add to 180°:

Angle AOB = (180 − 2b)° Triangle ACO is isosceles, so:

Angle OCA = Angle CAO = c° And, using Angles of a Triangle add to 180°:

Angle AOC = (180 − 2c)° And, using Angles around a point add to 360°:

there is 4 i cant find the 5th one
