Answer:

AOB = 55°

BOC = 87°

COD = 130°

AOD = 88°

Step-by-step explanation:

AOB = a°

= 55°

BOC = b°

= 87°

COD = c°

= 130°

AOD = 360°-AOB-BOC-COD

= 360°- a° - b° - c°

= 360° - 55° - 87° - 130°

= 88°

Step-by-step explanation:

a + b + c + x = 360°

if a=55°

b=87°

c=130°

then x=86°

calculate angles one by one

<AOB = a = 55°

<BOC = b = 87°

<COD = c = 130°

<AOD = x = 86°
