To solve this problem instead using the cosecant function, we would get: The reason that we got 23.7 here and 23.81 above is due to differences in rounding in the middle of the problem. = tan-1(1/ 3) = 30 or /6. Determine the angle of elevation of the top of the tower from the eye of the observer. Hence the ratio of their bases $\left(\dfrac{\ell x}{\ell} \right)$ is equal to the ratio of their heights $\left( \dfrac{1.8\, \text{m}}{6.0\, \text{m}}\right)$: \begin{align*} \dfrac{\ell x}{\ell} &= \frac{1.8 \, \text{m}}{6.0 \, \text{m}} \\[12px] watched, from a point on the
