Question

If $fraction numerator b over denominator c plus a end fraction plus fraction numerator c over denominator a plus b end fraction equals 1$ then

$A = 60^{\circ}$
$B = 60^{\circ}$
$C = 60^{\circ}$
$A = 90^{\circ}$

hint Hint:

To find the value of angle A we will solve the equation using the cosine formula .

The correct answer is: $A equals 60 to the power of ring operator$

In $triangle$ ABC,
