Chapter 9, Problem 20CT

To determine

To find the distance that the cone extends from the mast at water level.

Answer to Problem 20CT

The cone extends from the mast at water level at a distance of $DC=60.62ft$

Explanation of Solution

Given:

  

Calculation:

The distance DC can be found by use the formula,

  $\begin{array}{l}\mathrm{Tan}{60}^0=\frac{DC}{BD}\\ \Rightarrow DC=(BD)\mathrm{Tan}{60}^0\\ givenBD=\text{ 35 ft}\\ \text{Then, }DC=(BD)\mathrm{Tan}{60}^0\\ {\text{ = (35) Tan 60}}^0\\ \text{ =60}\text{.62 ft}\text{.}\end{array}$

Hence, the cone extends from the mast at water level at a distance of $DC=60.62ft$
