Slope is 5!
Equation:
13-8/9-10=5/1
y2-y1=x2-x1
um I dunno because I need points to ask a question sorry
Answer:
dude all you have to do is add it up its A or B
The 2 lines are parallel, so the 2 sides(e.g. 1 and 2/ 3 and 49) add up = 180 and In this case the 2 sides are equal as u can see from the original diagram so the angle of 2 is 180-49=131.
