Answer: m∠CAB=48°

Explanation:

From the given picture, there is a circle with center O and the measure of central angle ∠COB=96°.

We know that the angle which is subtended by an arc at the centre of a circle is double the size of the angle subtended at any point on the circumference.

Therefore,
\angle{COB}=2*\angle{CAB}


\Rightarrow\ \angle{CAB}=(1)/(2)\angle{COB}=(1)/(2)*96^(\circ)=48^(\circ)

Hence, m∠CAB=48°
