Ответ:24,5

Объяснение:В прямоугольном треугольнике против угла равного 30 градусов лежит сторона равная половине гипотенузы. То есть, из суммы углов треугольника находишь, что угол А равен 30 градусов. Значит ВС =49:2=24,5

I went to the airport and i was really excited. After all checking in I sat in a waiting room with a big smile. And finnaly I heard "Passengers fly number 1234 is fly out". After that I neded to take some water. Vending machine worked as slowly as a turtle and I was in anger! And sudenly I heard that my plane leaving in 3 minutes! I ran soo fast how I could. At the last moment I went on plane. It was a wonder because I did it myself and i was proud of me. I had my seat near the window. It was the beginning of my story. I texted mom that I`m good and sent her some photos. We started fly. I turned off my phone and enjoyed. I fell asleep fast, and I woke up just when we was in Czech Republic. We talk with mom by phone when went out of airport. I saw so beautiful town and I fell in love. I went to the hotel, left my things and went to excursion. Now i know many things about Czech. In the last day there after one of the restaraunt, in hotel i wanted to see night in Czech. It seemed like a dream, because it was unreal. All night i was in my balcony and saw that beautiful veiw. I was sad when I went in airport. But I wanted to see other countries. Fly to Bulgaria was great. When plane fly above town I could see part of the sea and nice buildings. Bulgaria - wonderful country whith unique nature and architecture. I could swim with aqualung in first time here. I was in aqualung costume and with balloon of air. I was in water from head to feet. When I touch the bottom of the Black sea I was so happy. I had excursions in Bulgaria too. Did you know that Bulgaria has the cleanest Black Sea coast? So after Bulgaria i went to Poland. For all of my trip in this country. I didn`t see any homeless animals! Because in Poland aren`t any homeless animals. Here I swim a looot! I liked the Baltic Sea in the Poland more than the Black sea in Bulgaria. And I visited the theaters. But my dream still was to visit Bolshoi Theater. Next country was Montenegro. I traveled by boat on island.In Montenegro I visited 3 islands. It's Mamula.There was very nice! And my fauvorite place in this trip is Russia! here is many amazing buildings and nature is cool. I preformed my dream and met Bolshoi Theater. Performances there is really legendary. When I was on performance I was as quiet as a mouse. When I sat in airport I was happy because my first trip was great! It is the end of the story about me and my wonderful birthday
