रेखा `(x-2)/a = (y-2)/b = (z-2)/c` तथा समतल `ax+by + cz + 6 = 0 ` के बीच का कोण है -

a/(y-z) = b/(z-x) = c/(x-y) then ax + by + cz =___

The average of a and b is 36. The average of b and c is 42. The difference between c and a is : a तथा b का औसत 36 है | b तथा c का औसत 42 है| c और a के बीच का अंतर है ?

The average of a and b is 36. The average of b and c is 42. What is the difference between c and a ? a तथा b का औसत 36 है | b तथा c का औसत 42 है | c तथा a के बीच कितना अंतर् है ?

If (x)/(b-c)=(y)/(c-a)=(z)/(a-b), prove that ax+by+cz=0

If x+y+z=19, x^2+y^2+z^2=133 and xz=y^2 , then the difference between z and x is : यदि x^2+y^2+z^2=133 तथा xz=y^2 है, तो z और x के बीच क्या अंतर है ?

If a + b + c != 0 then the number solutions (x,y,z) to the system (b + c)(y + z) - ax = b - c (c + a)(z + x) - by = c - a (a + b) (x + y) - cz = a - b is

If (x^2-yz)/a=(y^2-zx)/b=(z^2-xy)/c , show that (a+b+c)(x+y+z)=(ax+by+cz).
