    Length of Runway

    A pilot flying at an altitude of 1.8 km sights the runway directly in front of her. The angle of depression to the beginning of the runway is 31 degrees. The angle of depression to the end of the runway is 23 degrees. What is the length of the runway? Round to the nearest tenth of a kilometer.

    a. 1.2 km

    b. 0.9 km

    c. 1.3 km

    d. 1.0 km


    I got 1.2 km

    Is this right?
