didnt see that comin XD

"There is a special rule used in geometry (the Transversal Postulate) that involves angles and transversals. It says that if two parallel lines are intersected by a transversal, then the corresponding angles are congruent. "
You used the word "corresponding angles" yourself. So the 10x angle and the 4x+42 angle are congruent, which means that their measurements will be the same.
measure of angle = measure of angle
10x = 4x+42
solve for x; plug it into both sides and see what you get.
So now you have the measure of angles "4" and "8".
Angles 3 and 4 make a straight line, r. A straight angle is 180 degrees. You know the measure of angle 4; so what's the measure of angle 3?
