If in a triangle ABC: Cos A + Cos B + Cos C = 3/2 then what is so special about this triangle?
What is the range of the values of k such that k Cos A - 3 Sin A = k + 1
has a real solution?
Triangle ABC has a right angle at B. Let Q be along BC and P be along AB such that AQ bisects angle A and CP bisects angle C. If AQ = 9 and CP = 8√2, what is the length of the hypotenuse AC?
