Answer:

52 metros.

Step-by-step explanation:

En este caso debemos usar las identidades trigonométricas. La información por medio del enunciado es:

*Sombra proyectada, que mide 20 metros y sería el cateto adyacente

*Ángulo de inclinación que son 69°

Con estos datos podemos calcular el cateto opuesto que sería altura, por medio de la identidad de la tangente:

tan α = CO/CA

CO = tanα * CA

CO = tan(69) · 20 m

CO = 52 metros

Lo que quiere decir que la altura del edificio es de 52 metros.
