A- It will be smaller, because we're finding a part of a number, and it's no more than 100 percent.

Answer:
Step-by-step explanation:

Answer: 66 degrees
Step-by-step explanation:
Sum of the angle measures is 180, so:
71 + x + 49 + x + 72 = 180
2x + 192 = 180
2x = -12
x = -6
Meaning the measure of angle A = -6 + 72 = 66 deg.
