    |dw:1328140802166:dw| trigonometry. use tangent function formula. . tan A= opposite side/ hypotenuse. . given the hypotenuse and the angle, you can find the altitude of the plane. .

    \[\sin 18=\frac{x}{16500}\]

    tan = opposite/hypotenuse??????? jerwyn? I thought tangent was opposite/adjacent.

    How long will it take the plane to climb to an altitude of 10,000 feet? 16,000 feet?
