Best ResponseYou've already chosen the best response.1well we need a definition, what does it mean to be complementary angles?

Best ResponseYou've already chosen the best response.1ugh, supplementary angles that is

Best ResponseYou've already chosen the best response.1might as well find the definition of both, knowing what complementary and supplementary angles are wont hurt :)

Best ResponseYou've already chosen the best response.0two angles are supplimentary when they add up to 180 degrees

Best ResponseYou've already chosen the best response.1thats a good definition, so all we need to do is add the angles and equate it to 180 10x + 60 = 180 .... what should x be?

Best ResponseYou've already chosen the best response.0arent we supposed to subtract something

Best ResponseYou've already chosen the best response.1sure, it looks like that +60 is getting in the way, lets subtract it ... from BOTH sides 10x + 60 = 180  60 60  10x + 0 = 120 so, now we can focus on: 10x = 120 what would you attempt now?

Best ResponseYou've already chosen the best response.110, times what, is 120?

Best ResponseYou've already chosen the best response.1the 10x = 120, when x=12

Best ResponseYou've already chosen the best response.1and 10x + 60 = 180, when x=12

Best ResponseYou've already chosen the best response.0so 12 degrees is the answer (:

Best ResponseYou've already chosen the best response.1well, not 12 degrees, 10x degrees, x is just a number that makes that value of 10x degrees equal ,120 degrees

Best ResponseYou've already chosen the best response.0so then what is the answer ?

Best ResponseYou've already chosen the best response.1hmm, i just noticed that they choose to put it as 12 degrees. old tired eyes .... sure, lets pick the one thats a 12, if you want to tack on a degree notation, its fine apparently :)
