I assume based on the diagram above indicates that ON is a diameter of circle N, therefore we should find angle OML.
OMN = 180
We should find the value of x first,
180 = 8x + 15x + 19
Simplify23x = 161
Divide both sides by 23 and the answer will bex = 7 Then we should substitute the value of x15(7) + 19 = 124
So the angle OML is 124
