Question

HELP PLEASE PLEASEEEE!!! I put the problem in an attachment!

Answer 1

x=sqrt((4,6)^2 +(12,3)^2 -(4,4)^2)) =

Answer 2

can you make the calcules ?

Answer 3

Are you sure that works because that is only if those were right triangles. And if you do it that way you get 12.37 which is not one of the choices.

Answer 4

do you know how to do this?

Answer 5

Yes

Answer 6

So since the two angles are equal you simply use the law of sines. where theta=sin(4.4/12.3) which is the same as theta = sin(4.6/x)

Answer 7

so you set sin(4.4/12.3)=sin(4.6/x)

Answer 8

and i think you can get it from there.

Answer 9

the answer is 12.8 by the way.

Answer 10

i mean 12.9. same thing
