Given `(b+c)/(11)=(c+a)/(12)=(a+b)/(13)` for a `DeltaABC` with usual notation. If `(cos A)/(alpha)=(cos B)/(beta)=(cos C)/(gamma)` then the ordered traiad, `(alpha,beta,gamma)` has a vlaue

Given (b+c)/(11) = (c+a)/(12) = (a+b)/(13) for a Delta ABC with usual notation. If (cos A)/(alpha) = (cos B)/(beta) = (cos C)/(gamma) , then the ordered triad (alpha, beta, gamma) has a value:

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

If alpha,beta,gamma are the lengths of the altitudes of Delta ABC, then (cos A)/(alpha)+(cos B)/(beta)+(cos C)/(gamma)=

If cos alpha+cos beta+cos gamma=0; then prove that cos3 alpha+cos3 beta+cos3 gamma=12cos alpha cos beta cos gamma

If cos alpha+cos beta+cos gamma=0, then prove that cos3 alpha+cos3 beta+cos3 gamma=12cos alpha cos beta cos gamma

If cos alpha + cos beta + cos gamma = 3 then sin alpha + sin beta + sin gamma =

If cos(alpha + gamma)/cos(alpha - gamma) = cos 2beta then tan alpha, tan beta and tan gamma are

If cos^(-1)alpha+cos^(-1)beta+cos^(-1)gamma=3 pi then alpha beta+beta gamma+gamma alpha equals

If cos (beta-gamma)+cos(gamma-alpha)+cos(alpha-beta)=-(3)/(2) then

If cos(alpha+beta)sin(gamma+delta)=cos(alpha-beta)sin(gamma-delta) then the value of cot alpha cot beta cot gamma, is
