    Triangle & angle of elevation question

    Good Day,

    I'm almost losing sleep over an Elementary Math geometry question that I've posted. I could solve parts a and b.

    However, my answers to the questions from part c onwards vary largely to those provided by the book. The answers are next to the questions in the attachment.

    Help me!

    1. Unfortunately you didn't post your working so we can't see where you need some additional support.

    2. Besides that I've tried to varify the given answers and failed successfully. I'll post my results so you can check if you have got the same answers:

    c) 443.8
    d) 25.36
    e) i) 12.3
    e) ii) 25.9

    I apologise for not providing my working. However, your answers and mine are exactly the same.

    I was confused because this book hardly gives the wrong answers. My answers usually varied with the book's in terms of significant figures and/ or decimal places. But not this greatly.

    Thank you for taking your time then. However, if anyone managed to get the same answers as the book's, I'll be glad to know how they did it.
