@legomyego180 What do I do from there?

legomyego180 · Answer

Im not sure, what class is this?

Do you have answer choices to this cause I have one way but im not so sure

love_333 · Answer

@563blackghost @legomyego180

legomyego180 · Answer

Im not sure, there is a formula you can use to solve this but you dont learn it until later. I cant think of any other way to solve it though. Maybe @563blackghost will know

love_333 · Answer

No, I do not @563blackghost

legomyego180 · Answer

You dont know anything about sine and cosine yet do you?

love_333 · Answer

Yes, I do but I'm not very good at them yet

563blackghost · Answer

She can probably still use 

$\Huge{A=\frac{1}{2}(a \times p)}$

For this problem...

legomyego180 · Answer

Ever heard of law of sine and law of cosine?

love_333 · Answer

No? @legomyego180

love_333 · Answer

How would that work? @563blackghost

563blackghost · Answer

Hmmm....

To solve we would need to find the apothem as well as the side length....

Do you think that would work @legomyego180 ?

legomyego180 · Answer

$$Area = \frac{ (553)(525)\sin(53) }{ 2 }$$

legomyego180 · Answer

This is the correct way, I believe. http://www.mathopenref.com/triangleareasas.html

@legomyego180 Whoa When I do that I get 115931.9272 Isn't that a pretty big number for something like that?

legomyego180 · Answer

You would need to use a calculator

love_333 · Answer

I did use my calculator

legomyego180 · Answer

Your dealing with big numbers, area will be big, yup

legomyego180 · Answer

Thats what I got as well.

legomyego180 · Answer

You would still have to use law of sines using that method, @563blackghost. I think it would work though.

love_333 · Answer

Hahaha something about this equation just doesn't seem right, I almost want to skip it all together... XD

563blackghost · Answer

Yea mines incorrect I barely realized that each side was different so when I multiplied `234.25` I wasn't suppose to do that and I got your guys answer :P

legomyego180 · Answer

Its the correct way to do it.
Area = SideA*SideB*Cos(C)/2

love_333 · Answer

@legomyego180 That is the way I worked it and turned it in.

legomyego180 · Answer

Sweet.
