An airplane is at a cruising height of 9,850 feet. if the angle of depression to the runway is 15°, what is the ground distance, to the nearest foot, from the point directly below the airplanes location to the runway? include a sketch that shows all known information and clearly shows what you need to find. show all work and give the answer rounded to the nearest foot.

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
