Starting with the fact that angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, use a two column proof to prove that consecutive interior angles a and b are supplementary. (5 points) statement reason 1.a and b are supplementary 1. angle a is 145 deg and angle b is 35 deg, the two angles add up to 180 degrees explain what the result of your proof tells you about angles a and b. specifically, if you measured one angle, what would you know about the other? (2 points) what you would know is if you measure one angle and then subtract it from 180 you get the other angle.

We can simplify it by combining like terms
We get -7x -3x = -10x and -10x+8x = -2x
then we get -2x + 2 = -8
-2x = -10
x = 5
