Answer:
The measure of angle A would be 78 degrees.,
Step-by-step explanation:
In order to find this, we must first note that parallel lines intersected by a traversal are equal in angles. This means that A would be equal to the missing angle of the straight line that includes 40 degrees and 62 degrees. Therefore we can use those two measures and set equal to 180.
40 + A + 62 = 180
102 + A = 180
A = 78
