A water tower is located 441 feet from a building. From a window in the building, an observer notes that the angle of elevation to the top of the tower is \( 37^{\circ} \) and that the angle of depression to the bottom of the tower is \( 26^{\circ} \). How tall is the tower? height \( = \) How high is the window from the ground? window is Report answer accurate to 2 decimal places. If it helps, there is a similar picture on page 486 of your Stewart text (see \#55).

Beyond the Answer

To determine the height of the water tower and the height of the window, we can break this down using some trigonometry. 1. **Calculating the Height of the Window:** For the angle of depression \( 26^\circ \): \[ \text{Height of window} = 441 \cdot \tan(26^\circ) \approx 441 \cdot 0.4877 \approx 215.28 \text{ feet} \] 2. **Calculating the Total Height of the Tower:** For the angle of elevation \( 37^\circ \): \[ \text{Total height of tower} = 441 \cdot \tan(37^\circ) \approx 441 \cdot 0.7536 \approx 332.44 \text{ feet} \] Finally, the height of the tower would be: \[ \text{Height of tower} = \text{Total height} - \text{Height of window} \approx 332.44 - 215.28 \approx 117.16 \text{ feet} \] So, the final answers are: - The height of the tower is \( 117.16 \) feet. - The height of the window is \( 215.28 \) feet. Enjoy your calculations and the interesting interplay of angles and heights!
