Please help to solve. Thanks.
Thanks for the help.
How do you know that the height of the orange inner triangle is 3?
It’s in the question diagram. Can be hard to see because of the photocopy quality but it’s there.
Oh… it’s given in the question? Lol. I was scratching my head wondering how to get the height! I was throwing all kinds of sin and cos things to the problem, but then I realised it was only a P5 question. Dark magic 🙂 🙂
I couldn’t see it at first too. Luckily I copied the question onto a virtual whiteboard and cranked up the brightness so it was just barely visible. Photocopied worksheets are bad for this reason.
