a single light hangs from a beam above the floor of this dilapidated warehouse.
there are two posts, both of which are a foot tall, separated by a distance of 15 feet. the light casts a 3 foot long shadow from the left post and a 2 foot long shadow from the right post.
figure out how high the light is hanging above the floor.
