Melody: Hi Melody, and likewise! I appreciate the explanation, and as for more help, it isn't necessary thanks to CPhills answer.
CPhill: Hi, thanks for the detailed explanation. Definitely makes sense. And that was nice of you to take the time to create a picture of the situation.
heureka: I'm a bit confused by your use of sin rather than tan...? Wouldn't that result in a totally different answer? Yet, you have arrived at the correct answer.
Rom and CPhill:
Yes, evidently quite a workout! Thank you both for taking the time to do it and explain it so methodically. I feel like my comprehension of the answers you gave to this particular problem has increased my confidence in converting word problems to workable algebra formulas more than perhaps any other word problem I've recently encountered. Much appreciated!
Thanks for the tip; done, and will be sure to do in the future. And its great to see you too! Haha, nice glasses, yes. How's the weather in Sydney this time of year?
