    I could use some help with this to clarify some things. Thanks



    The angle of elevation of the top of a tower is 38 degreese from a point (A) duesouth of it. The angle of elevation of the top of the tower from another point ( B), due east of the tower is 29 degreese. Find the height of the tower if the distance AB is 50m.


    BTW, I did not write this problem down. I found it somewhere else and pasted it here. I went through this problem with a friend and we had conflicting views on how to answer it. I am pretty sure he is right, but some clarification would be helpful. After I get a fews answers I'll put the answers we had.

    Let the top of the tower be T and the bottom of the tower be O. Let the height of the tower be x.

    OA = x/tan(38), OB = x/tan(29).

    Substitute into (OA)^2 + (OB)^2 = 50^2 and solve for x.

    Mr. F,
    IF you make a typo, what's the best way to let you know?
    or is that considered an intentional instructional issue?

    I make typos all the time. Keeps the OP on his/her toes. However, IF you spot a mistake you should feel free to point it out if you want to. The worst that will happen is that I'll ban you (only kidding).
