To answer this question first you set up a picture to look like a right triangle, then you just do right triangle trig. to find the height of the pole, find the angles in side the triange

anonymous · Answer

then use those angles, sine tangent cosine not sure which one i didnt do the problem, and do the trig. on a graphing calculator and you should get your answer

anonymous · Answer

Okay so I used the tangent one and I got 135.1 and so the answer would be 135 feet then? If I am understanding how this is suppose to work,
