The equations of the sides AB and AC of a triangle ABC are (λ+1) x+λ y=4 and λ x+(1-λ) y+λ=0 respectively. Its vertex A is on the y - axis and its…
The equations of the sides AB and AC of a triangle ABC are $\displaystyle (\lambda+1) x+\lambda y=4$ and $\displaystyle \lambda x+(1-\lambda) y+\lambda=0$ respectively. Its vertex A is on the y - axis and its orthocentre is $\displaystyle (1,2)$. The length of the tangent from the point C to the part of the parabola $\displaystyle y^2=6 x$ in the first quadrant is :
