Step-by-step explanation:
If the parallelogram is being rotated the side length will stay the same as it is in the current state.
Both of those times are in two standard deviations, so the percent would be 95%.
Generally speaking, 19/8 is 2.375 so they should be 28.5 inches apart. however you gotta factor in how thick the shelves themselves are :)
In a regular hexagon, each side is contained in a separate equilateral triangle with side of 2-units. That makes six equilateral triangles with side 2-units.
Further, each equilateral triangle of side 2-units contains four (4) equilateral triangles of side 1-unit.
Therefore the total number of equilateral triangles of side 1 units in a hexagon with side two units is 6*4=24.
