Frances Spears · Answer 1

117 degrees

Step-by-step explanation:

According to Alternate Exterior Angles Theorem, and then Definition of linear pair, the angle A and the angle that is 63 degrees are supplementary:

Thus, we can use the following equation to find A:

A+63=180

A=180-63

A=117 degrees
