its a question in the section before they teach us law of sines

Answer 7

so it should be answered without law of sines

Answer 8

\[\frac{6}{\sin(42)}=\frac{x}{\sin(62)}\] or \[x=\frac{6\sin(62)}{\sin(42)}\] and a calculator

Answer 9

similar for \(y\)

Answer 10

you good from there?

Answer 11

sorry my internet stopped working

Answer 12

yeah it is the site, not you
you good now?

Answer 13

is this sine law?

yes

Answer 15

\[\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}\] where the upper case angle is opposite the lower case side

Answer 16

if you know any three of the four numbers, you can find the fourth, which is why the first step was \[\frac{6}{\sin(42)}=\frac{x}{\sin(62)}\]

Answer 17

okay. thanks i understand now.

Answer 18
