If `x,y,z` are respectively perpendiculars from the circumcentre on the sides of the `DeltaABC`, the value of `a/x+b/y+c/z-(abc)/(4xyz)=`

If x,y,z are respectively perpendiculars from the circumcentre on the sides of the Delta ABC, the value of (a)/(x)+(b)/(y)+(c)/(z)-(abc)/(4xyz)=

If x, y, z are perpendicular distances from circumcentre to the sides of Delta^("le")ABC respectively then (xyz)/(abc){(a)/(x)+(b)/(y)+(c)/(z)}=

If the lengths of the sides vec(BC), vec(CA) and vec(AB) of the triangle ABC be a:b:c respectively and the lengths of perpendicular from the circumcenter upon vec(BC), vec(CA) and vec(AB) be x, y, z respectively, then prove that, a/x + b/y + c/z = (abc)/(4xyz) .

If H is the orthocentre of DeltaABC and AH=x, BH=y, CH=z then (abc)/(xyz)=

If in Delta ABC , the distance of the vertices from the orthocenter are x,y, and z then prove that (a)/(x) + (b)/(y) + (c)/(z) = (abc)/(xyz)

If in Delta ABC , the distance of the vertices from the orthocenter are x,y, and z then prove that (a)/(x) + (b)/(y) + (c)/(z) = (abc)/(xyz)

If in Delta ABC , the distance of the vertices from the orthocenter are x,y, and z then prove that (a)/(x) + (b)/(y) + (c)/(z) = (abc)/(xyz)

If a^x=b,b^y =c,c^z=a , find the value of xyz.

If a^x=b, b^y=c,c^z=a then the value of xyz is
