Question

If a,b,c are the sides of the triangle ABC such that $open parentheses 1 plus fraction numerator b minus c over denominator a end fraction close parentheses to the power of a end exponent open parentheses 1 plus fraction numerator c minus a over denominator b end fraction close parentheses to the power of b end exponent open parentheses 1 plus fraction numerator a minus b over denominator c end fraction close parentheses to the power of c end exponent greater or equal than 1$
Then the triangle $A B C$ must be

Right angled
Isosceles
