Chapter 4: Problem 37
The bottom of the basket of a hot-air balloon is parallel to the level ground. One taut tether line 144 feet long is attached to the center of the bottom of the basket and is anchored to the ground at an angle of \(72^{\circ},\) as shown in the figure below. Which of the following expressions gives the distance, in feet, from the center of the bottom of the basket to the ground? A. \(\frac{144}{\cos 72^{\circ}}\) B. \(\frac{144}{\sin 72^{\circ}}\) C. 144 \(\tan 72^{\circ}\) D. 144 \(\cos 72^{\circ}\) E. 144 \(\sin 72^{\circ}\)
