The bisector divides the angle in half. According to the condition of the problem, it is specified that the OD ray is the bisector of the AOM angle, and it is also specified that the AOD angle = 72⁰.
In order to find the corner of the MOD you need:
72 * 2 = 144 (⁰) – angle MOD.
The bisector OD divides the AOM angle in half, which means that the AOD angle = the DOM angle. In order to find the angle of the MOD, it is necessary to find the sum of the angles of the AOD and the DOM. Accordingly, in order to find the angle of the MOD, it is necessary to multiply the degree measure of the angle of the AOD by 2.
