Hey here is ur answer
in triangle DCB
m of angle d+m of angle c+ measure of angle b=180
m of angle b is 30
m of angle c is 20+20 =40
m of d is ?
so
30+40+d=180
70+d=180
d=180-70=110
now o is centre hence DO is angle bisector
therefore measure of ODC =ODB
therefore measure of ODB and ODC is equal to measure of D
hence measure of ODC is 55 degree
hope it helps!!!
