Sine, Cosine, Tangent Applications

The Sine, Cosine and Tangent functions are often applied to real world scenarios.

Example 1

What is the height of the tree below?

$tan(16) = \frac{opp}{adj} \\ tan(16) = \frac{14}{\red x} \\ \red x = \frac{14}{tan(16)} \\ \red x = 48.8$

problem 1

$tan(55) = \frac{opp}{adj} \\ tan(55)= \frac{\red x }{ 57} \\ \red x = 57 \cdot tan(55) \\ \red x = 81.4$
