------------------
Use the Cosine Law to find the angles.
I don't know what you mean by 87 42 42

There is no solution because the sum of the shorter two sides of any triangle is ALWAYS GREATER THAN the longest side. In this problem, the sum of what are supposed to be the two shorter sides is 42"+42"=84", which is less than what is supposed to be the longest side 87". So those three lengths cannot be the sides of a triangle.
