Answer 7

do you know what mean supplementary angles ?

Answer 8

Yes

Answer 9

write me please here

Answer 10

1 and 2 are supplementary => what about them ?

Answer 11

=> 1 +2 = 180 degrees

yes ?

Answer 12

Yes

Answer 13

and given again that 2 + 3 = 180 degrees too

yes ?

Answer 14

Yes

Answer 15

so

1 +2=180
2 +3 = 180
------------
=> 1+2 = 2+3 subtract 2 from both sides and will get

1 = 3

hope helped

Answer 17

ok. hope you understand it now

good luck

bye bye

after you subtract from both sides m2 you get this m1=m3

Answer 21

ok. ?

Answer 22

I understand that part too but that wasn't what I was asking for thank you for helping me though.
