El punto más alto de un repetidor de televisión situado en la cima de una montaña se ve desde un punto del suelo p bajo un ángul
Maksim231197 [3]

Answer:

El repetidor tiene aproximadamente 90.494 metros de altura.

Step-by-step explanation:

Al término de esta solución podemos encontrar el diagrama geométrico con toda la información derivada de lo descrito en el enunciado de la pregunta. Aquí designamos la altura del repetidor con la letra h, medida en metros. Procedemos a resolver el modelo a partir de la Ley del Seno:

\frac{30\,m}{\sin 3^{\circ}} = \frac{s}{\sin 67^{\circ}}

s \approx 527.651\,m

\frac{s}{\sin 156^{\circ}} = \frac{h}{\sin 4^{\circ}}

h \approx 90.494\,m

El repetidor tiene aproximadamente 90.494 metros de altura.
