I'll use A,B,C in place of alpha,beta,gamma.
 
 
Given info is: 
b = 17 
c = 9 
A = 34 degrees
 
 
Angle A is between sides b and c. 
We can use the side angle side (SAS) area formula for a triangle.
 
 
area = 0.5*side1*side2*sin(angle between those sides) 
area = 0.5*b*c*sin(A) 
area = 0.5*17*9*sin(34) 
area = 42.7782571155121 
area = 42.8 
Your calculator needs to be in degree mode.
 
 
Answer: 42.8 square units (approximate)
