The OC ray is the bisector of the AOB angle. Find the AOC angle if the AOB angle = 86

Consider the AOB angle.
By condition, OC is the bisector of this angle.
In order to find the value of the angle AOC, you should remember the rule about the bisector.
A bisector is a line or ray that halves an angle.
Thus, in order to find the angle AOC, the following equality can be written.
AOC = AOB: 2.
By condition, the value of the angle AOB is given.
The AOB angle is 86 °.
Substitute this AOB into the above equality and calculate the AOC.
AOC = 86 °: 2.
AOC = 43 °.
Answer: AOC = 43 °.
