Speaking Task 1. Choose the question from the card on the topic Entertainment and fedia^ prime prime and be ready to answer it after the teacher starts the conversation. Produce a speech by giving extended answers to the questions. Share your ideas with the class. Teacher organizes a Socratic seminar, which helps him/her to assess learners while they are speaking on the toplic Entertainment and Media and he/she prepares and cuts down questions and expressions beforehand. Learners sit in a circle and answer the question using in their speech some formal and Informal expressions to present logically connected information to their classmates. Expressions: Stating an opinion The way I see it... Sorry to interrupt, but... Is it okay if I jump in for a second? Can I add something here? Can I throw my two cents in? Not necessarily Interrupting If I might add something..... I beg to differ No, I'm not so sure about that That's for sure Expressing disagreement I'd say the exact opposite I have to side with somebody (name)on this one I was just going to say that In my opinion Expressing agreement If you ask me.. That's exactly how I feel As far as I'm concerned. If you want my honest opinion..... You have a point there That's not always the case
1)9 , 16, 12 см
Объяснение:
1)сначала находим катеты (3х и 4х) по теореме пифагора : 16х^2+9х^2= 625; х^2=25; х=5 см. один катет - 15 см , а второй - 20 см;
пусть одна часть гипотенузы равна у, тогда вторая -25-у (высота делит гипотенузу на две части ).
за формулой 15^15= у*25; у=9см, тогда 25-у= 16 см. (это проекции)
высота = 12 см (вымотав в квадрате = 9*16)
2) гипотенуза = корень из 81+ корень из 144 (под одним корнем )= 15 см
одна часть гипотенузы равна х, вторая -15-х. тогда 25=15х-х^2;
ну и находим х(это будет проекция , которая будет 15-х)
