There is 180deg in a half circle, and 360deg in a full circle. complementary angles complete a half circle perfectly. angle z is complementary to 111deg. z= 180 - 111= 69deg z= 69deg There are 360 total degrees in the figure because it makes one total revolution. y= 360- 69- 94- 88 y= 109deg Check - 109 +69 +94 +88= 360
