| The OM beam divided the angle CОК equal to 90 into two angles CОМ and MOK. The СОМ angle is 2 3/5 times greater than the МОК angle. What are the angles COM and MOC equal to?
Let the angle MOC have a degree measure x °. Then, if it is known that the angle CОМ is 2 3/5 times greater than the angle MOK, then its value will be (2 3/5 * x) °. Because according to the condition of the problem, the angle CОК is equal to 90 °, and it consists precisely of the angles CОМ and MOK, then the following equality will be true:
x + 2 3 / 5x = 90,
3 3 / 5x = 90,
18 / 5x = 90
x = 90/18 * 5,
x = 25.
Accordingly, the angle СОМ will be equal to:
25 * 2 3/5 = 25 * 13/5 = 5 * 13 = 65 (°).
Answer: the MOC angle is 25 °, the COM angle is 65 °.
