Since AB is a straight line, and straight lines are 180 degrees, you can add the two 62 degree angles.
62+62=124
180-124=56
angle x is 56 degrees
A quotient means division, so you can get rid of the third and fourth choices. It says "opposite" so that means negative.
The answer is the second choice:
A=-3 and i think any value of 'a' makes those equation infinite solution because expression has same variable both side.
