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°

(Correct me if i am wrong)

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°

1.  x/6>3  multiply both sides by 6

x>18

So a. and c. are both greater than 18

2.  

-4x<32  divide both sides by -4  (and remember to reverse direction of inequality sign because of multiplication/division by a negative value!)

x>-8

So three value of this infinite set are -7, -6,  -5  :P

3.

x/6≥3 multiply both sides by 6

x≥18

So three value of this infinite set of solutions are 18,19,20
