In a triangle a = 13 , b = 14, c = 15, r =

If a = 13, b = 14 , c= 15 then r=

In the triangle A B C, a=13, b=14, c=15 then sin (A)/(2)=

If, in Delta ABC, a = 13, b = 14, c = 15, then : sin (A//2) = ....

In a triangle ABC, if a=13,b=14 and c=15, then angle A is equal to (All symbols used have their usual meaning in a triangle.)
