When the axes are rotated through an angle `alpha`, find the transformed equation of `xcos alpha+ysin alpha=p`.

Statement - I : When the axes are rotated through an angle alpha the transformed equation of x cos alpha + y sin alpha = p is X = p Statement - II : A = (2,3), B= (3,5), C = (-1,4) are the vertices of a triangle and the origin is shifted to the point (1,1) then the centroid of the triangle is ((4)/(3),4) Which of the above statement is correct :

When axes rotated through an angle alpha the transformed equation of x cos alpha + y sin alpha = p is

If the axes are rotated through, an angle theta , the transformed equation of x^(2) + y^(2)=25 is
