Question

6 $overrightarrow{co}$ is an angle bisector. if $mangle cob = 33^circ$, then what is $mangle aob$?
$mangle aob = \square$

Explanation:

Step1: Define angle bisector property

An angle bisector splits an angle into two equal angles, so $m\angle AOC = m\angle COB$.

Step2: Calculate total angle $m\angle AOB$

$m\angle AOB = m\angle AOC + m\angle COB = 2 \times m\angle COB$
Substitute $m\angle COB = 33^\circ$:
$m\angle AOB = 2 \times 33^\circ$

Answer:

$63^\circ$
