                                        x2+y2+2gx+2fy+c=0

condition for orthogonal,
2*g*10=c+4
perpendicular fron center to x=2 is radius..
f2=22g
put g=-x and f=-y
hence,y2=-22x

If the orthocentre of a triangle is at (4,5) and the centroid is at (3,3), where is the circumcentre located? Answer is (2.5,2). Please explain.
 
 
so.. centroid is dividing Orhtocentre and circumcentre in 2:1 internally use section formula if the circumcentre is (x, y) for X-coordinate: 3 = (4*1 + 2* x)/ 3 ….....(1) 9 =(4*1 + 2*...

( m+2 )sinA + (2m – 1)cosA = ( 2m+1 ) then find tanA. (the answer is 3/4)
 
 
(m+2) Sin A +(2m-1) Cos A = 2m+1--------1 we know that , Sin A =(2 tan(A/2))/(1+tan 2 (A/2) and Cos A = (1-tan 2 (A/2))/(1+tan 2 (A/2) let tan(A/2) = k and it in first equation We get,...
