You are very close My answer is in the 74_._ _ (that's seven hundred forty something point something)
To start you off:(2*0.15*10^-9*sin(17.42))/2 = 4.49061*10^-11 (wavelength)

(6.63*10^-34)/(4.49061*10^-11) = (P or the momentum) follow all of the other posts to get you to your answer.
Gook luck!!!!
