sin= соотношение противоположного катета на гипотенузу. sin0.3=9/x0.3x=9x= 9/0.3x=30-гипотенузавторой катет:√30^2-9^2=√819=28.6приблизительно

The mystery : 7 am , 21st August , 1911 and just another Monday morning at the Louvre . Guards , cleaning staff , maintenance workers and curators were all working in the building before reopening its doors to the public on Tuesday . While they were working , though at some time between 7 and 8:30 am , someone entered the empty Salom Carre , unhooked the Mona Lisa from the wall and carried it off down a stairwell . The stairs led to a door , locked from the outside , but somehow , the theif escaped thought it . At first , museum workers assumed that the official photographer was shooting pictures of the painting in his studio .An afternoon and evening passed by and it wasn't until the following day that they realised the precious artwork was missing . It was the beginning of a huge international search for the missing Mona Lisa . The only clue was the discovery of the paintina's heavy frame discarded on the stairs . There were conflicting rumours in the newspapers ; the Mona Lisa was now in Switzerland , South America , or in a small apartment in the Bronx , New York . No one knew who really committed the crime and how .
The Solution On that fateful Monday morning,an Italian man called Vincenzo Peruggia,once a worker at the Louvre,knew the building very well.The guard on duty in the Salon Carre admitted leaving his post for a few minutes at around 8 am.While the guard was away,Peruggia lifted the Mona Lisa from her four iron pegs,entered the stairwell ,removed the painting's frame and hurried down the steps.Then ,he unlocked the door and escaped from the museum.Peruggia hid the painting in his small Paris flat where it remained,in a cupboard , for over two years . Later ,Peruggia took the Mona Lisa to Florence ,Italy ,and attempted to sell it.It was there,back in the Mona Lisa 's hometown ,that the police finally caught Peruggia .
