The triangle sum conjecture simply states all 3 interior angles inside a triangle must add up to 180 deg.

Given/assumed:  Triangle with interior angles A, B, and C, with opposing sides a, b, and c (side a is opposite angle A, etc.)  Question is asking for angle A and length of sides a and b, although it appears b is also stated as 7 cm.  However, this problem cannot be solved with only ONE side and NO angles given.
