Answer 1

First, welcome to openstudy!

Answer 2

thank you!

Answer 3

If you do not know the rules, then you can read them here:

Answer 4

Now, what can you interpret from the data?

Answer 5

1 = 2, so?

Answer 6

it needs to be written in a two column proof btw. forgot to add that.

Answer 7

well linear pairs add up to 180 degrees

Answer 8

so angle 1 and 2 are supplementary by the supplements theorem

Answer 9

so one = 2

Answer 10

excuse me

Answer 11

so what do 3 and 4 equal? 3 = 4, btw

Answer 12

they equal 120* my friend @tori72

Answer 13

yes, 180-120 is 60, problem is i don't know how to write this down as a two column proof

Answer 14

so, now you need to gather the info

Answer 15

this is what i have so far, statements: 1. angles 1 and 2 form a linear pair angle 1=2(angle 2) (given). 2. angles 1 and 2 are supplementary (supplements theorem). 3. angles 1 + 2 = 180 (definition of supplementary angles).

Answer 16

if angle 1=2 and they add to180 deg. they each must be 90
something wrong with this question??

Answer 17

angle 1 is equal to twice angle 2
