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
