All my friends are very active people. We like indoor and outdoor activities. So that’s why we spend a lot of time together and we have so much in common.
Still each of us is a very unique person. Some our hobbies are pretty different and today I would like to tell you about one my passion.
My favorite hobby is volleyball. I have been playing volleyball since I have been 6. First time I came to play volleyball with my father. My parents wanted me to be interested in something, so they were trying different things. I tried to play football few times,basketball and even dancing classes. When my father took me to play volley I was curious about this game, because I watched it before only on TV.
I remember my first game. I was a loser. I didn’t know how to play, but only ran around the square. I was the youngest one and didn’t listen to anybody. The only thing I wanted to be part of the team. Later on my coach explained me the rules and importance to follow them. After few months I have become a good player.
Today I pay a lot of attention to school and my lessons. It’s not easy to manage with the school and all hobbies. Still very often I go to play volley with my friends or classmates. If I see someone wants to join us I am always happy to have a new-player in our team even if he doesn’t know the rules. I can explain the rules with pleasure.
In future I would like to continue to play volley but I am not sure I will succeed. I hope in future I will live not far away from a gym or a place where I can play it. But today I can really enjoy this time. I am so much happy my parents made a right decision. Thank to them I have found so many hobbies, but volleyball is not just hobby. Volley is my passion. Volley is the place where I have met the best teachers and best friends
Обозначим ключевые точки треугольника как показано на рисунке.
Для начала найдем гипотенузу прямоугольного треугольника ABC по теореме Пифагора:
AB2=AC2+BC2
AB^2=120^2+35^2
AB^2=14400+1225=15625
AB=125
Рассмотрим треугольники ACD и ABC.
∠ADC - прямой, так как AD - высота и, следовательно равен прямому углу ACB.
∠CAD - общий для этих треугольников.
Следовательно, по первому признаку, треугольники ABC и ACD подобны.
Значит мы можем записать пропорцию:
AC/AB=CD/CB
120/125=CD/35
CD=(120*35)/125=(120*7)/25=(24*7)/5=33,6
Ответ: 33,6
