In a triangle ABC, if A is (1,2) and equation of the medians through B and C are x + y = 5 and x = 4 respectively, then B is : (1,4) (7,-2) (4,1) (-2,7)
Hello student, The equation of median through B is x+y = 5. The point B lies on it so the coordinates of B are (x 1 , 5-x 1 ) Now CF is a median through C, so coordiantes of F i.e. mid-point...
