Best ResponseYou've already chosen the best response.0Well the angles in a triangle add up to 180 degrees total, for starters.

Best ResponseYou've already chosen the best response.0Yeah so what would the formula to solve it look like? would it be x+x+20=180 ?

Best ResponseYou've already chosen the best response.1alright so, the equation is 3x+20+x=180 , do you know why?

Best ResponseYou've already chosen the best response.0Because the one angle is 3 times the other?

Best ResponseYou've already chosen the best response.1no no, the largest would be 3x wouldnt it? so it'd be 3(40) so 120, whereas the whole equation would be 120+40+20 = 180 right?

Best ResponseYou've already chosen the best response.0it can't be 60. think about it: with an equilateral triangle, each angle is 60 degrees. any other triangle will have angles larger than 60.

Best ResponseYou've already chosen the best response.1Does anyone think this is correct? Work courtesy of @Ms_Worth Let the smallest angle = x Then the third angle is ( x + 20 ) The second angle is 3x Together they add up to 180 x + 3x + ( x + 20 ) = 180 5x + 20 = 180 5x = 160 x = 32 < x was already defined as the smallest angle The other angles are ( x + 20 ) = 32 + 20 = 52 3x = 3 ( 32 ) = 96 < largest angle Answer: the largest angle is 96 degrees CHECK 32 + 52 + 96 = 180
