Designing a drawbridge A drawbridge is 150 feet long when stretched across a river. As shown in the figure, the two sections of the bridge can be rotated upward through an angle of 35°. (a) If the water level is 15 feet below the closed bridge, find the distance d between the end of a section and the water level when the bridge is fully open. (b) Approximately how far apart are the ends of the two sections when the bridge is fully opened, as shown in the figure? Exercise 33 d 35° 35° 150'-
