I used sine law to find 31.44 and 55.1 degrees but i'm not sure it's right now i'm confused. what should i do? please help.
Your answers are correct:
$\displaystyle \frac{\sin \alpha}{6} = \frac{\sin 73^0}{11} \Rightarrow \alpha = 31.44^0$.
$\displaystyle \frac{\sin \beta}{11} = \frac{\sin 31.44^0}{7} \Rightarrow \beta = 55.1^0$.
The question as originally posted by the OP is in no need of clarification.
