In the figure below, lines 1 and 2 are parallel, and lines 3 and 4 are parallel. If the measure of ∠a is 125°, what is the measure of ∠b? (10 POINTS + BRAINLIEST ANSWER)
Well a flat line equals 180 so you use the angle of a and try to find the other side of the angle, so you you do 180 subtracted by 125 which you get 55. Since B is parallel to the angle, the answer is 55 degrees.
