Answer: 142

Step-by-step explanation: I can prove my answer by showing you this, if we add 52+90 (because of the 90 degree angle marked on the right) that = 142 then we take 180 -142 = 38 then we know the angle of the marked triangle, were not done. Then we need to subtract then from 180 which equals 142! its magical how math works! (180 because all straight lines = 180 degrees if not then they arent straight)
