1125 feet above the ground
question: At what height did the plane start its descent?, context: [Pre-Calculus] Angles of depression. "To approach the runway, a small plane must begin a 9o descent starting from a height of 1125 feet above the ground. To the nearest tenth of a mile, how many miles from the runway is the airplane at the start of this approach? (Hint: 1 mile = 5280 feet)" I have no idea where to even start. This is an online course I'm taking, and it doesn't tell me anything I need to know in the reading material. What's the formula I need to use to solve this, and what even is this?
