The OB beam divides the right angle MOK into two angles so that the angle KOB is 0.6

The OB beam divides the right angle MOK into two angles so that the angle KOB is 0.6 of the MOK angle. Find the measure of the angle MOB.

1. Determine the value of the angle KOВ, formed by one side of the right angle and the ray drawn from its top, since it is known what part it is from the right angle.

90 * 0.6 = 54 °.

2. Let us find what the degree measure of the angle of the MOВ is equal to.

90 – 54 = 36 °.

Answer: The angle of the MOВ is 36 degrees.
