How to find the largest angle of a triangle

0. Let a, b and c be the three interior angles of a triangle, where a ≤ b ≤ c. It is given that 4 c = 7 a. Find the maximum possible value of c, i.e. the largest interior angle. The question is now maximizing c with the constraints. a + b + c = 180. a ≤ b ≤ c. 4 c = 7 a. I try to consider a = 4 7 c but I have no idea how to proceed.The easiest way to solve it is to add (1), (2), and (3) which yields 2 (a+b+c)=15 or a+b+c=7.5 By deducting (1), (2), and (3) from this equation, we get c=3.5, a=2.5, b=1.5. The largest angle is the one across side c. We find it using cosine law. If the angle is C we have 3.5^2 = 2.5^2+1.5^2–2*2.5*1.5*cos (C). 12.25 = 6.25+2.25 -7.5*cos (C)In order to understand this property which says that the side opposite the greater angle is the longest side, observe the triangle given below. In this triangle, ∠B is the greatest angle. Thus, the side AC is the longest side.
