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 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 then the value of xyz is:

If a^(x)=b,b^(y)=c and c^(z)=a then find the value of xyz

Let x,y,z are positive reals and x +y+z=60 and x gt 3. Maximum value of xyz is :

If x,y and z are three numbers such that x+y=13,y+z=15 and z+x=16,then the value of (xy+xz)/(xyz) is:

ABC is a triangle with sides 3, 4, 5. Let P be a point inside the DeltaABC , and let x, y and z be the length of peripendicular dropped from P on side AB, BC and AC respectively. What can be the maximum value of X+Y+Z.
