I need to know how to find the measurements of angles 1,2,and3 step by step

so to find angle one you just subtract the other angles from 180°
180°-33°-92°=55°
angle 2 is going to be equal to the adjacent angle every time so it's equal to 92°
angle 3 you just subtract everything from 360°
360°-90°-115°-92°= 63°
