1 and 2 are a linear pair. M1=x-35, and m2=x+83. find the measure of each angle

Question

I need help, can someone please walk me through this?
Thank you

Answer 1

a linear pair adds up to a straight line: 180°
So, now you just solve
x-35 + x+83 = 180
x = 66
Now use that to find the angle measures.

Answer 2

<1 and <2 from a linear pair. M<1=x. M<2=2x-60
What is the degree for m<1 and m<2

Answer 3

Option A is the answer

Answer 4

<1=31°,<2=149° Is the correct answer so it's A
