I have used a calculator for this and got 192. Question how do I find these without a calculator is there a method that anyone knows?
[math]tan(30°) = \frac{ \sqrt{3}}{2}[/math]0
[math]tan(60^{\circ}) = \sqrt{3}[/math][math]12 × \frac{\sqrt{3}}{2} +2 × \sqrt{3} = 8\sqrt{3}[/math]

I think everyone missed it, but I think, on your first line of working, you mean \(\displaystyle cos 30^o=\frac{\sqrt{3}}{2}\)

I certainly missed it I was probably suffering from radiation sickness at the time

@The Highlander also said this in post#5. Well spotted to both.

Not "everyone"! (See 2nd paragraph of post #5.) ?
Hmmm, I always read through your posts too. ?

Yes, it was a joke, admittedly pretty bad ? I'll whistle and inconspicuously walk away before I get sent to the corner

Sorry Highlander. I did miss that (even though it is in a very large font)!

Even with your cat's eyesight? ?
That's one of the reasons I prefer a larger font. ?
