Answer:
1 = 37° 2= 53° 3=106° 4=74°
Explanation:
I apologize in advance since I am not the best at explaining but I'll do my best:
All triangles add up to 180° since you already know 106° you can subtract 106° from 180° to get 74° so you divide that by 2 to get angle 1 since both angles will be the same (since all the triangles are isosceles triangles) now since it's a rectangle all angles add up to 90° so subtract 37° from 90° to get angle 2 now you only have 3 and 4 left 3 is 106° since it's the same as the first triangle now to find four since you know angle 2 you know both of the bottom angles are 53° now 53 times 2 equals 106° so you subtract 106° from 180° and get 74°
