If <BFA=3r+12 and m<= -8+210, find m<AFE.

How do you work this out?

Your posting does not make any sense to me.

BFA and AFE are vertical meaning they are also supplementary (= to 180) so you you would set up an equation like 3r+12+-8r+210=180 then combine like terms you should get -5r+220=180 then subtract 220 from 180 leaving -5r=-42 then divide -5 from-42
