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:
}{a}\ =\ \frac{\sin(B)}{b}\ =\ \frac{\sin(C)}{c})
Solve
}{a}\ =\ \frac{\sin(C)}{c})
for
)
Which you can do because you know (or can look up) 
, , and )
Then look up
\right))
which gives you the measure of angle 
.
Repeat the law of sines process for angle 
.
