Step-by-step explanation:
The angle that represents an exterior angle of is: d. ∠CAB
An exterior angle of a triangle is an angle outside the triangle that is adjacent to an interior angle of a triangle, and also shares same side together.
An illustration of an exterior angle of a typical triangle has been shown in the diagram attached below.
The angle that is marked green is an exterior angle.
Analyzing the diagram given for this question, the only exterior angle of triangle ABF from the list of answer choices given is <CAB.
Therefore, the angle that represents an exterior angle of is: d. ∠CAB
