Step-by-step explanation:

5. In the figure, O is the centre of the circle.

Construction: Join OD.

In A AOD,

AO = OD (radii)

angle DAO= angle ADO=48^

In triangle CC ,

CO = OD (radii)

angle OCD= angle ODC=31^

From figure, it's clear that,

angle ADO+ angle ODC= angle ADC

48^ +31^ = angle ADC

angle ADC=79^

angle AOC=2* angle ADC

=2*79^

=158^

therefore angle AOC=158^
