\(\displaystyle arc \ adb \ = \ 290^0\)

\(\displaystyle The \ degree \ measure \ of \ a \ minor \ are \ (ab) \ is \ the \ measure \ of \ the \ corresponding \ central \ angle\)
\(\displaystyle \ (angle \ acb).\)
\(\displaystyle angle \ acb \ = \ 70^0 \ = \ arc \ (ab).\)
\(\displaystyle The \ degree \ measure \ of \ a \ major \ arc \ (adb) \ is \ equal \ to \ 360 \ minus \ the \ measure \ of \ the\)
\(\displaystyle \ corresponding \ minor \ arc \ (ab).\)
\(\displaystyle Hence, \ arc \ (adb) \ = \ 360^0- \ arc(ab) \ = \ 290^0.\)
\(\displaystyle \ (angle \ acb).\)
\(\displaystyle angle \ acb \ = \ 70^0 \ = \ arc \ (ab).\)
