tarea en el cole

En la clase de matemática estuvimos usando la técnica de la Tangente (Tg), el Seno (Sen) y le Coseno (Cos) para encontrar ángulos y lados de triángulos rectángulo. Por ejemplo, una actividad decía lo siguiente: Un helicóptero vuela  una altura de 1000 pies sobre una cumbre de 5210 pies de altura.Un segundo pico, mas alto, se ve desde la primera montaña y desde el helicóptero. Desde el aparato, el angulo de depresión es de 45° y desde la primera cumbre, el angulo de elevación es de 60°. a. Calcular la distancia de una cima a la otra. b. Calcula la altura de la segundo pico.  Para este primero separamos los dos triángulos y analizamos los datos que nos brinda la consigna, en este caso, al tener las dos el calor de C en decidimos hacer igualar las dos tangentes para obtener la incógnita A. Triángulo amarillo                             Triángulo naranja                  tg 60= (A-5210):C                      tg 45= (6210-A): C         C= (A-5210): tg 60   

In my school we had a writing competition with our teacher Andrea in which we had options we could decide to write about. In one they gave us several sentences and we should use one in any part of our story. So here is my story, hope you enjoy it. I will never forget that day, that tragic day. I think about it every day and every night. It all started an early morning, by the time I’d woken up my phone was full of messages, a very common thing since my final exams were starting and my mom, as always, was all over me with her speeches of why I shouldn’t be late and that I must remember everything by heart. After a short breakfast and a quiet revision of my notes, I hopefully went to take my test. Never leave the house mad with someone, you never know when is the last time you get to talk to them It is really strange why things happen when you least expect them. In my case, by the time I was starting my exam I got a call from my mother. I thought it was just another silly c
