Intellectual power of a dragon pack?

Dragons have to meet for a brainstorm in a convention center. The delegates have to be selected to provide the maximum efficiency of the brainstorm session. A dragon has any amount of heads, and for any N, any amount of N-headed dragons is available if needed. The problem is that the size of the convention center is limited so no more than 1000 heads can fit into the assembly hall. The intellectual power of a dragon pack is the product of head numbers of dragons in the pack. How should an optimum pack look like (the total number of dragons, the head number distribution)?

Molly flies a kite that is attached to a string that is 100 meters long. The angle of elevation of the kite is 36 degrees. If she is holding the string 1 meter above the ground, how high is the kite?

COuld you guys describe to me, or make it someone if possible how the diagram of the right angle triangle would look like. I don't understand the 1m part, it throws me off.
