@sweetburger Are you good with math?

Answer 8

Answer 9

I'm not the best at proofs but I will give it my best go:

the first statement (1) is already given in the problem so you would simply write "given"

Answer 10

please do

Answer 11

I am not exactly sure what they are looking for #2 or #3 ("definition of linear pair"?)

for #4 this is just the definition of supplementary angles (angles that add up to 180)

Answer 12

for #5 the triangle sum theorem states that all angles in a triangle sum to 180, so you would write an expression that sets the sum of angles 1, 2, and 3 equal to 180

Answer 13

#6 is just setting the expressions from 4 and 5 equal to each other "substitution property of equality"

Answer 14

I think so, since you subtract <3 from both sides to go from 6 to 7

Answer 15

and is 6 substitution?

Answer 16

yes

Answer 17

wow thnx for your time !!
