@hartnn Can you help me with this quick question?

hartnn (hartnn):

yes.

hartnn (hartnn):

exterior angle = sum of interior angles. here, exterior angle = 110 and interior angles are x and 60

OpenStudy (anonymous):

Do I add 110 and 60 to get 170 then subtract by 180 OR subtract 60 from 110 to get 50?

hartnn (hartnn):

exterior angle = sum of interior angles. 110 = x (sum) 60 110 = x+60

OpenStudy (anonymous):

Oh so it would be 50 then correct?

hartnn (hartnn):

yes, x= 50 is correct :)
