minus-squareLifeInMultipleChoice@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up8·edit-21 day agoNah, the imagery tricks you. 180 degrees to a line. 180 degrees inside a triangle. So you can gather the inside unlabeled angle on the triangle on the left is only 80 degrees: (180-[60+40]) So you then know it’s 100 on the right side of that +35 leaves you with 45 degrees left for the top of the right one. 180-45=. 135 degrees
