Question

Ayuda Por favor con esas aplicaciones de las razones trigonometricas.

Answer 1

Miguel,

Recordemos
         sen = (cat op)/(hip)      cos = (cat ady)/(hip)      tag = (cat op)/(cat ady)

Aplicando la relacion apropiada en cada caso

1)    (tag)
                     altura/8 = tag53
                        altura = 8tag53
                                     tg53 = 1.327
                        altura = 8(1.327)
                                  = 10.616
                                                          LA ALTURA ES 11 m
2) (sen)
                  2300/d = sen(90 - 25)
                              = se65
        2300/(sen65) = d
                                   sen65 =0.906
               d = 2300/(0.906)
                  = 2538.631
                                          DEBE RECORRER 2539 m
3)  (tag)
               75/sombra = tag43
               75/(tag43) = sombra
                                     tag43 = 0.933
               75/(0.933) = sombra
                     80.386 = sombra
                                                   MEDIDA SOMBRA ES 80 m
4) (tag)
                  6380/d = tag1
                           d = 6380/(tag1)
                                 tag1 = 0.017
                           d = 375294.118
                                                      OBTUVO 375,294 km
