The answer would be option D.
10a^3 + 91a^2 + 54a - 792
        
             
        
        
        
Answer:
As they triangles are congruent, we can say that, angle A = angle O
So, angle A = 105+25 =130
A = 180 - 130 = 50° all angles in a triangle add up to 180)
Soo 50° is the answer, 
I'm not too sure about it but I think this is correct, hope this helps, correct me if I'm wrong....
