x-y=0 and x2+y2=1 are respectively the perpendicular bisectors of the sides AB and AC of a triangle ABC. If the vertex is A2, 3, then the equation of the side BC is

  1. A x-2y+1=0
  2. B x+2y-3=0
  3. C 2x+y-3=0
  4. D x-2y=-4
Verified Solution

Answer & Solution

Correct Answer

(A) x-2y+1=0

Step-by-step Solution

Detailed explanation

Given :- x-y=0 is perpendicular bisector of side AB. ∴ Equation of side AB is. x+y+λ=0 ∵ It passes through A2,3 ∴ λ=-5 ∴ Equation of AB is, x+y-5=0   ....1 Solving…
