Answer 1

Answer:

Arrange the mirror in between them.

Answer 2

The mirrors can be placed at the leftmost bottom corner and right-side.

Step-by-step explanation:

There are two mirrors to be placed.

The reflection in the mirrors should be such that, it is seen by the other lighthouses.

If we keep one mirror on the left-most bottom corner at about a 45-degree angle, we would observe that the bottom three mirrors can have their reflections and they can also see each other.

The second mirror can be placed near the right side below the fourth lighthouse to see the reflection.

See the figure attached.
