    Trigonometry-right triangles from protractor
    A person stands 35.0 m from a flagpole. With a protractor at eye level, he finds that the angle the top of the flagpole makes with the horizontal is 25.0 degrees. How high is the flagpole?(the distance from his feet to his eyes is 1.770 m.)

    Just use the law of tangents.



    Then, add on the height of the observer.
