2. A cierta hora el sol se observa con un ángulo de elevación de \( 55^{\circ} \). Calcula la altura del árbol que proyecta una sombra de \( 10,89 \mathrm{~m} \). 3. Desde un punto situado a 30 m arriba en un faro se observa un pequeña embarcación con un ángulo de depresión de \( 33^{\circ} \). Calcula la distancia, al pié del faro a que se encuentra la embarcación.

Quick Answer

Para calcular la altura del árbol, multiplicamos la longitud de la sombra por la tangente del ángulo de elevación: \( h = 10,89 \cdot \tan(55^{\circ}) \approx 15,55 \, \text{m} \). Para encontrar la distancia a la embarcación, dividimos la altura del faro por la tangente del ángulo de depresión: \( d = \frac{30}{\tan(33^{\circ})} \approx 46,19 \, \text{m} \).
