In a triangle `A B C`, the bisectors of angles `Ba n dC`lies along the lines `x=ya n dy=0.`If `A`is `(1,2)`, then the equation of line `B C`is`2x+y=1`(b) `3x-y=5``x-2y=3`(d) `x+3y=1`A. 2x+y=1B. 3x-y=5C. x-2y=3D. x+3y=1 |
Answer» Correct Answer - B The reflections of A in the two angle bisectors will lie on the line BC, So, (2,1) and (1,-2) will lie on BC. The equation of BC will be `y+2 = ((1+2)/(2-1))(x-1)` i.e., 3x-y=5 |
