Let the circumcentre of a triangle with vertices A ( a, 3), B ( b, 5) and C ( a, b ), ab >0 be P(1, 1). If the line AP intersects the line BC at the…
Let the circumcentre of a triangle with vertices $\displaystyle \mathrm{A}(\mathrm{a}, 3), \mathrm{B}(\mathrm{b}, 5)$ and $\displaystyle \mathrm{C}(\mathrm{a}, \mathrm{b}), \mathrm{ab}>0$ be P$\displaystyle (1, 1)$. If the line AP intersects the line BC at the point $\displaystyle \mathrm{Q}\left(\mathrm{k}_1, \mathrm{k}_2\right)$, then $\displaystyle \mathrm{k}_1+\mathrm{k}_2$ is equal to :
