Question

Law of sines question, PLEASE HELP!:)

Answer 1

another?

Answer 2

Yeah I thought I would create a new thread since the other one got kinda lengthy, I have 3-4 questions in total. But i want to be able to see each one clearly.

Answer 3

good idea

Answer 4

Alright, so I know that we need to use the law of sines (DUH)
1.3/sin56=b/sin68

Answer 5

dont forget to label the sides appropriately

Answer 6

yeah that looks good

Answer 7

i would do this

Answer 8

so then I just do 1.3sin56/6sin68 right?

Answer 9

or wait other way around; 6sin68/1.3sin56 ???

Answer 10

yes

Answer 11

and that is what b is equal to

Answer 12

\[\frac{b}{\sin(68)}=\frac{1.3}{\sin(56)}\]
\[b=\frac{1.3\sin(68)}{\sin(56)}\]

Answer 13

b=3.55

Answer 14

that is not what i get

Answer 15

oh yeah, I dont know where i got the 6

Answer 16

Answer 17

b=1.45

Answer 18

do we need to solve for the other side though?

Answer 19

no

Answer 20

oh because it is a isocelese

Answer 21

it is also 1.3 because you have an isosceles triangle

Answer 22

right

Answer 23

since the two angles are the same it makes the sides equal as well?

Answer 24

yes

Answer 25

I have more questions so I am going to create another thread, once again:) thanks @satellite73
