[" In a triangle "ABC" ,if the sides "a,b,c" are roots of "x^(3)-11x^(2)+38x-40=0." If "sum((cos A)/(a))=(p)/(q)," then find "],[" the least value of "(p+q)" where "p,q in N" ."]

If in a triangle ABC a,b,are roots of the equation x^(3)-11x^(2)+38x-40=0 then sum(cos A)/(a) equal to:

In DeltaABC , if the sides a,b,c are the roots of x^(3)-11x^(2)+38x-40=0 then the value of (cosA)/(a)+(cosB)/(b)+(cosC)/(c)=

In a Delta ABC, the side a, b, and c are such that they are roots of x^(3) -11x ^(2) +38x -40=0. Then the value of (cos A)/(a )+ (cos B)/(b)+ (cos C)/(c ).

If p^(3)-q^(3)=(p-q)((p-q)^(2)-xpq), then find the value of x is (a) 1 (b) -3(c)3(d)-1

If the sum of square of roots of the equation x^2+(p+i q)x+3i=0 is 8, then find the value of p and q , where p and q are real.

If the sum of square of roots of the equation x^2+(p+i q)x+3i=0 is 8, then find the value of p and q , where p and q are real.

Given a triangle ABC with sides a=7,b=8 and c=5. If the value of the expression (sum sin A)(sum(cot A)/(2)) can be expressed in the form (p)/(q) where p,q in N and (p)/(q) is in its lowest form find the value of (p+q)
