Step-by-step solution to a trigonometry problem that asks you to calculate the height of a tower in two cases. The first is simpler, and the second, "height of an inaccessible point," is a bit more complex since the distance to the base of the tower is unknown. This can also be applied to a mountain or any other object whose distance to the base cannot be measured.
I've uploaded the video of the step-by-step solution for the second case: • Resolución del Sistema del vídeo "Calcular...
