30 feet. And you don't have to round it to the nearest foot. It's exactly 30 feet.
An airplane flying at an altitude of 2600m, approaching an airport runaway located 48km away, is descending at an angle of 3.1 degrees, rounded to the nearest tenth of a degree. Construct a right triangle. Horizontal is 48. Verticle (opposite) is 2.6. Hypoteneuse is 48.07 by pythagorean theorem. The inverse sine of (2.6 / 48.07) is 3.1 degrees.
