we are given an angle elevation of 7 degrees and a descent height of 5 miles. In this case, to determine the distance of the runway at the start of the approach, we can use the formula tan theta = 5/x where theta is equal to 7 degrees and x is the element to be determined. x is equal to 40.72 miles
