I believe since it's a supplementary line, your answer will be 180-57

This would make your angle 123°. My apologies if I am wrong. I have not taken Geometry in a Year or two.
The answer is 147

180-33 = 147

The angle of POQ is 33 as 180-90-57 = 33

Then the angle of NOM is the same as POQ because they are opposite

Therefore NOM is 33

180-33 = 147
