Algebra ->  Trigonometry-basics -> SOLUTION: A 70 foot tall monument is located in the distance. From a window in a building, a person determines that the angle of elevation to the top of the monument is 13° and that the ang      Log On

Let d be the distance from the building to the monument, horizontally.


Then equation you need to solve is  d*tan(13°) + d*tan(8°) = 70 feet.


From the equation,  d =  =  = 188.17 ft.    ANSWER
