Trigonometry

[supple otter]

you can work out the distance of george to the plane using pythagoras

and the distance of peppa to the plane using trigonometry

also youve posted the Q twice so if you can remove the other post pls

[frank island]

How I’m confused Icl what you mean by that what would you use ?

[supple otter]

which bit

[frank island]

Part A

[supple otter]

part a wants you to work out the distance that george and peppa are to the plane and then compare to see who is the shorter distance away

[frank island]

What calculations would you do for A and B that’s what I’m confused about

[supple otter]

I would use pythagoras to work out the distance george is to the plane. So 346^2 + 3900^2 = (distance george to plane)^2

[frank island]

That makes sense now what about part C ??

[supple otter]

that was only for part a

you need to do two calculations for part a

the other will be sin(83) = 3900 / (distance peppa to plane)

then compare the distances

[frank island]

I’ll try that thanks I think I would probs know the rest except C how would you do that ?

[supple otter]

it wants that angle

[frank island]

How would you find that angle ?

That’s confusing hella

[supple otter]

there is a large grey right angled triangle with adjacent side 680 and hypotenuse 1000

[frank island]

What would you do though ? Cosine rule ?

Or am I wrong ??

[supple otter]

oh wait it might not be right angled myb

yh cosine rule

work out the distance from mommy to peppa and then you'll have 3 sides of the triangle

[frank island]

How would you do B?
