As time goes by, so does the inch. But, it says that only 1/4 falls, not 1 1/2. Say Y is constantly one. At hour one, it should be 1 1/4. At hour two, it should be 1 2/4 (or 1 1/2). At hour three it should be 1 3/4. At hour four, only now will it become 2 inches. They added to many in this table.
Good luck!

That meeting place is called the orthocenter.
Answer:
since there are 18 of these isosceles triangles in the polygon, then multiply this by 18 to get area of the polygon with 18 sides is equal to 28.56497087 square units. you can round this to as many desimal digits as required. each of those little triangle with a vertex angle of 20 degrees is an isosceles triangle.
