Step-by-step explanation:

Finding angle 1:

52 + angle 1 = 180

angle 1 = 128

Finding angle 2:

128 (angle 1) + angle 2 = 180

angle 2 = 52

Finding angle 5:

52 + 47 + angle 5 = 180

angle 5 = 81

Finding angle 3:

angle 2 + angle 3 + angle 5 = 180

52 + angle 3 + 81 = 180

angle 3 = 47

Finding angle 4:

angle 3 + angle 4 = 180 OR angle 4 + 47 = 180

47 + angle 4 = 180

angle 4 = 133
