The altitude of a mountain peak is measured as shown in the figure to the right. At an altitude of 14,554 feet on a different mountain, the straight-line distance to the peak of Mountain A is 27.1243 miles and the peak's angle of elevation is θ-518000. (a) Approximate the height (in feet) of Mountain A. (b) In the actual measurement, Mountain A was over 100 mi away and the curvature of Earth had to be taken into account. Would the curvature of Earth make the peak appear taller or shorter than it actually is? 27.1243 mi 4,554 ft (a) The height of Mountain A is approximately feet. (Do not round until the final answer. Then round to the nearest foot as needed.) Enter your answer in the answer box and then click Check Answer. Check Answer Clear All part remaining 2 3 4 5 6
