Recall the formula for the area of a regular n-gon with side length a.

#

No idea sorry

#

It’s not taught for gcse maths 😭

are you retared you autistic monkey this shi ez

#

ok

#

sorry

How tf this guy a helper

Plus I live in the uk so we learn different formulas πŸ€·β€β™‚οΈ

#

Note, however, that the side lengths are different.

#

You can circumvent that by recalling the variant of this formula in terms of the circumradius R instead of side length, though.

#

im pretty sure

#

ur supposed to use the formula

#

1/2 ab sinC

#

since this is "GCSE"

verbal river
#

the area should be just sine of the angle

#

add the areas of the triangles up to find the ratio

#

3sin(60) : 4sin(45)

#

so

#

3root3/2 : 4/root2

#

3root3/2 : 2root2

#

3*3/2:2root6

#

9:4root6

#

therefore

#

1:4/9root6

#

@stiff fiber

#

this would be the gcse method

#

therefore

#

Below what?

verbal river
#

bro

#

a levels

amber knot
#

I don't understand what you mean. Did you mean "a level" or "levels"?

verbal river
#

did you forget that the uk exists πŸ’€

amber knot
#

Well, I know that the UK exists, but what does that have to do with this?

verbal river
#

cause that's how it works in the uk

amber knot
#

Hm. Well, ok.

#

Still not sure why you write "a levels".

verbal river
amber knot
#

Oh. OHH. You meant A-levels!

#

Now I get it.

#

Well, I still don't know how that works, but whatever. This would be my approach. I think it's appropriate for grade 8 and above.
The area of a regular n-gon with circumradius R is S(n, R) = (1/2)nR^2 sin(2Ο€/n). In our case the circumradius is the same, so we get:
S(8)/S(6) = 8sin(Ο€/4)/(6sin(Ο€/3)) = 8(√(2)/2)/(6(√(3)/2)) = 4√(6)/9

education is such a joke here

#

do nothing in 7,8,9

Oh, that's a shame...
