SUMMARY
The discussion centers on solving a right triangle problem without knowing the length of the base, specifically a bottom line of 16 meters. A user inquires how their friend calculated the hypotenuse, denoted as $d$, using only the angle $\theta = 0.19$. The solution provided utilizes the cosine function, where $d$ is derived from the formula $d = \dfrac{16}{\cos{\theta}}$. This method confirms that it is possible to find the hypotenuse using trigonometric principles without direct knowledge of the base length.
