## Answers

In the equation 40+70+?=360, they are trying to find the last angle. First they would add 40 and 70, which is 110. So 110+?=360360-110=?360-110=250Well this is wrong, because every angle in a triangle adds up to 180 degrees. If you are adding up the angles in a quadrilateral, only then it adds up to 360 degrees. So they did everything right, but they didn't use the right "total degrees"This is what it was supposed to look like.40+70+?=180110+?=180180-110=?180-110=70?=70♡ Hope this helped! ♡♡ Also thank you so much for 31 points. ♡✿ Brainiest is appreciated! ✿❀ 0ranges ❀
