so it should be answered without law of sines

anonymous · Answer

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

anonymous · Answer

similar for $y$

anonymous · Answer

you good from there?

anonymous · Answer

sorry my internet stopped working

anonymous · Answer

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

anonymous · Answer

is this sine law?

anonymous · Answer

yes

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer
