minus-squareSiethron@lemmy.worldlinkfedilinkarrow-up24·2 个月前135, that’s not a 90 degree angle in the problem. Just visually.
minus-squareSaharaMaleikuhm@feddit.orglinkfedilinkarrow-up7·2 个月前Oh that’s just a cheap trick. You are right, it’s 80 degrees despite looking like 90 degrees.
minus-squareStomatalinkfedilinkEnglisharrow-up1·2 个月前You are right that is 80° so the value of x will be 135°
minus-squareLifeInMultipleChoice@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up8·edit-22 个月前Nah, 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
minus-squaretetris11@lemmy.mllinkfedilinkarrow-up6·2 个月前Also if you add up all visible angles you get 135, so I’m sold on that alone. No no no, I won’t hear any rebuttals.
I think 125
