Ok

anonymous · Answer

Thank you!

ganeshie8 · Answer

hey in option C the angles do add up to 180
so C cannot be the answer

anonymous · Answer

Well it says the one that can not add up to 180

ganeshie8 · Answer

yes a triangle cannot be formed if the angles dont add up to 180

in which option the angled don't add up to 180 ?

ganeshie8 · Answer

*angles

anonymous · Answer

The question says to find the one that can not exist.

ganeshie8 · Answer

yes the angles in optionC form a triangle as they add up to 180.

so thats not your answer

ganeshie8 · Answer

try last option :

30+45+55 = 130

which is not 180. so a triangle cannot exist with these angles
