- Find the angle of elevation of a rifle barrel, if a bullet fired at 1,500 feet per second takes 2 seconds to reach a height of 750 feet. Give your answer to the nearest tenth of a degree.arrow_forwardMountain Climbing Several mountain climbers are located in a mountain pass between two peaks. The angles of elevation to the two peaks are 0.84 radian and 1.10 radians. A range finder shows that the distances to the peaks are 3250 feet and 6700 feet, respectively (see figure). (a) Find the angle between the two lines. (b) Approximate the amount of vertical climb that is necessary to reach the summit of each peak.arrow_forward
