Find the value of C if in a triangle S=13,a=8, and b=7.

If two sides of a triangle are 8 cm and 13 cm, then the length of the third side is between a cm and b cm. Find the values of a and b such that a is less than b.

If two sides of a triangle are 8 cm and 13 cm, then the length of the third side is between a cm and b cm. Find the values of a and b such that a is less than b.

With usual notations, if in a triangle A B C(b+c)/(11)=(c+a)/(12)=(a+b)/(13) , then prove that: (cosA)/7=(cosB)/(19)=(cosC)/(25)
