Option (3). 120° will be the answer.
Step-by-step explanation:
By using the theorem of secants intersecting externally,
Measure of angle formed by two secants, from a point outside the circle is half the difference of the measures of the intercepted arcs.
m∠C =
36° =
72° = °
= 72 + 48
= 120°
Therefore, Option (3) is the answer.
