Say I'm at an unknown distance from a mountain, called point P, and I estimate the angle of elevation to the top of the mountain is 13.5 degrees. Then I move to point N, which is 100 meters closer to the mountain, and I estimate the angle of elevation to be 14.8 degrees. What is the height of the mountain?

  • Maths -

    review the basic trig functions. You will see that if the height is h,

    h cot13.5° - h cot 14.8° = 100
