Answer: To solve this problem, we can use trigonometry and the relationship between angle, distance, and altitude in a right triangle.
Let's denote the angle the pilot was flying at takeoff as θ. We can then use the tangent function to find θ, since:
tan(θ) = opposite/adjacent
In this case, the opposite side is the altitude the pilot reached (1500 feet), and the adjacent side is the distance the pilot traveled before reaching that altitude (2 miles = 10560 feet). So we can plug in these values and solve for θ:
tan(θ) = 1500/10560
θ = tan⁻¹(1500/10560)
θ ≈ 7.67 degrees
So the pilot was flying at an angle of approximately 7.67 degrees at takeoff from the runway.
