I thought it was C, because the only way for the triangle to be isosceles given both conditions is for BC = AC , and that's not possible because side AC + BC (assuming they are the same length) would equal AB. And the third side of the triangle must be greater than the sum of the other two sides or less than the difference of the other two sides. So given both conditions, should we be able to say for sure that the triangle is not isosceles?
The
OG says it's E though. Please help.
Answer should be E
even if we cosider both 1) & 2) consider the below examples:
Case 1--> x= 30, y=100 & third angle= 50
Case 2--> x=45, y=90 & third angle =45
here both 1) & 2) are satisfied but there is contradiction in result, i.e. in one case traingle is issoceles, in other it is not, for the same conditions. Hence E
