It is important to remember the "Angle Addition Postulate" in order to solve this exercise.

You have this larger angle:

According to the "Angle Addition Postulate", if the point "C"  is in the interior of , then the measure of this angle can be obtained by adding the angle and the angle .

You can observe in the figure that:

Then you get that:

Therefore, the correct answer is Option A.
