Best ResponseYou've already chosen the best response.2well the 3 angles add up to 180 so we can write an equation any ideas ?

Best ResponseYou've already chosen the best response.0Nope that's why I'm asking for help. If I knew how to set it up I could most likely do it.

Best ResponseYou've already chosen the best response.2x + 2x + x  10 = 180 makes sense?

Best ResponseYou've already chosen the best response.2the 3 angles are on the left and 180 on the right so now if you solve for x youll find the measure of the first angle second angle = 2 8 x

Best ResponseYou've already chosen the best response.2add up the first 3 terms x + 2x + x = ?

Best ResponseYou've already chosen the best response.04, sorry I forgot to count both of the Xs for 2x.

Best ResponseYou've already chosen the best response.2right 1 + 2 + 1 = 5 in same way x +2x + x = 4x

Best ResponseYou've already chosen the best response.2* lol thats 4 NOT 5!!

Best ResponseYou've already chosen the best response.2so we have 4x  10 = 180 add 10 to both sides 4x  10 + 10 = 180 + 10 4x = 190 x = 190/4

Best ResponseYou've already chosen the best response.2now divide 190 by 4 to get x then multiply the result by 2 to get the values of 2x which is the values of the second angle

Best ResponseYou've already chosen the best response.0190 / 4 = 47.5 47.5 * 2 = 95
