In a dark night, you have only one light source in your room. But you have two mirrors, one is concave and another is convex. Which mirror will you use to make the room lighted?

In the given figure, two mirrors $\mathrm{P}$ and $\mathrm{Q}$ are situated at an angle of $60°$ 

with each other and a ray of light is incident on mirror $\mathrm{P}$ at an angle of $55°$. What is the value of angle $\mathrm{A}$ if the ray again reflected by the mirror $\mathrm{Q}$?
