Question

I need help with these.

Answer 1

Anyooooone? It's due soon

Answer 2

Too much reading effort LOL... but fine ill help ish

Answer 3

I know! And thanks

Answer 4

The first one is law of sines.

SinA/a=SinB/b

Answer 5

or let me write that more clearly...

(Sin(A))/a=(Sin(B))/b

Answer 6

where A and B are the angles

Answer 7

and a and b are the side lengths.

Answer 8

you have all the numbers so just plug and chug

Answer 9

for the second part you need to use the law of cosines to find either angle C or sidelength c

Answer 10

a^2=(b^2+c^2)-2bc*cos(A)

Answer 11

again you have all the numbers so just plug and chug.

Answer 12

(oh and the two possible values come from two possible interpretations of sin)

Answer 13

(so basically you need to use the law of cosines twice or something)

Finding the areas
A=(1/2)*a*b*sin(C)

Answer 14

basically ive given you all the formulas, all you need to do is plug and chug and remember that there are two possible values when you do the arc sin in the initial part of the problem.

So yeah you should be able to do it.

Answer 15

I need to go write my 5 page essay due tomorrow so gl!
