    A plane is reported to have crashed landed 34.1376 Kilometers from its initial altitude of 70,000 ft where the emergency radio call occurred and was tracked on radar. The in flight black box recorder was slightly damaged and some of the raw data was missing. What was found is that the plane had a precise speed of 700 mph at the all the way down. From the time of emergency till it hit the ground 1 hour transpired.

    What is the angle of descent of the plane? Pick one of the following and explain?


    A) 0 degrees

    B) 20 degrees

    C) 70 degrees

    D) 45 degrees

    E) The plane never crashed

    F) 35 degrees

    G) your answer

    Given the statements in the initial question E is obviously wrong.
    We don't do your homework for you.

    Need some help with your homework? Hint - you'll likely be using the Pythagorean Theorem, although straight trigonometry would also work for this. Think about what the definition of tangent is.
