Question

Ms. Abreau is flying to Florida for the 90° Angle Conference, where the temperature s just right. Her plane is 1200 feet in the air and the runway is 3400 feet horizontally away. What is the angle of depression formed from the plane to the runway ? Round to the nearest tenth if necessary and just the number please in your answer, we know it is degrees.

    Answer:

    19.4 degrees

    Step-by-step explanation:

    Using the SOH CAH TOA trigonometry identity

    Given

    Height of plane from the ground= 1200 = adjacent

    Horizontal distance = 3400ft = Adjacent

    Required

    angle of depression theta

    tan theta = opp/adj

    tan theta = 1200/3400

    tan theta = 12/34

    tan theta = 0= arccos.3529

    theta=  (0.3529)

    theta = 19.4 degree

    Hence the angle of depression is 19.4 degrees
