Question

what is the measure of angle cab in circle o?
24°
48°
72°
96°

Explanation:

Step1: Identify angle type

The 48° angle is an inscribed angle subtended by arc CB. Angle CAB is also an inscribed angle subtended by arc CB.

Step2: Apply inscribed angle theorem

Inscribed angles subtended by the same arc are congruent, so their measures are equal.
$\angle CAB = 48^\circ$

Answer:

48°
