This one is actually quite similar to a past DSE question (I forgot which year, just too lazy to check). EDIT: Not DSE 2021 problem, but still it looks kind of like a past paper question. I think it's 2020? Again, I'm not bothered to check. With co-geom questions, the first step is almost always to draw a diagram. Did you do that? Can you show any progress you've made?

Our Math teacher give this Mock paper for our revision before the exam.
We have tried our best to imagine what the diagram should look like, but different member draws differently, we can’t confirm which one is accurate.
Please kindly show us what the diagram is.

Thank you so much

Other stuff should fall into place quite naturally. Here's a head start for (b)(ii): Generally speaking, there are no trivial ways to find an angle when dealing with co-geom problems (what I mean by trivial, I mean something that you can just "see"). Unless there's something clever, which I can't find, finding where D is seems to be the most sensible thing to do. UID216418 帖子931 精華0 積分114 閱讀權限40 在線時間1492 小時 註冊時間2011-5-4 最後登錄2021-6-18  查看詳細資料 TOP
