The problem asks you to find $$\lfloor 0.785\rfloor$$. The definition of $$\lfloor x\rfloor$$ for an arbitrary real $x$ is given in the first paragraph of the problem. If you don't understand that definition, I suggest an exchange. You give a detailed explanation of what you do and don't understand in that sentence. This helps me understand what parts of explanations may not be clear, and helps me hopefully explain things better in the future. In exchange, I describe the confusing parts. (I am not the author of the problem, of course.)
 
This is confusing! Yazan975 thanked Evgeny Makarov for his response but did not answer any of the questions or do any of the things that Evgeny Makarov suggested!
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
