[qquad [x cos theta=,y cos(theta+(2 pi)/(3))=z cos(theta+(4 pi)/(3))" then the "],[,(1)/(x)+(1)/(y)+(1)/(z)=]]

If x cos theta=y cos(theta+(2 pi)/(3))=z cos(theta+(4 pi)/(3)), then write the value of (1)/(x)+(1)/(y)=(1)/(z)

If xcostheta=ycos(theta+(2pi)/(3))=zcos(theta+(4pi)/(3)) , then (1)/(x)+(1)/(y)+(1)/(z)=?

If x cos theta=y cos(theta+(2 pi)/(3))=z cos(theta+(4 pi)/(3)), prove that xy+yz+zx=0

If x/(costheta)=y/(cos(theta-(2pi)/3))=z/(cos(theta+(2pi)/3)) then x+y+z is

If x*cos theta=y*cos(theta+(2 pi)/(3))=2*cos(theta+(4 pi)/(3)) then evaluate xy+yz+zx

If x\ costheta=y cos(theta+(2pi)/3)=z cos(theta+(4pi)/3) , then write the value of 1/x+1/y+1/zdot

If x\ costheta=y cos(theta+(2pi)/3)=z cos(theta+(4pi)/3) , then write the value of 1/x+1/y+1/zdot
