You can put this solution on YOUR website!

You need the Law of Cosines to find the measure of side . Once you have done that, you need the Law of Sines to find the other two angles.

Law of Cosines:

Plug in the numbers and do the arithmetic. Don't forget to take the positive square root to find from at the end.

Law of Sines:

Once you know the value of , use:

Solve

for

Which you can do because you know (or can look up) , , and

Then look up

which gives you the measure of angle .

Repeat the law of sines process for angle .
