You can use the Ruffini's rule. The answer using this method is,

And you can see that the multiplicity of the zero x=-4 is 2, and the multiplicity of the zero x=+3 is 1.
3x+2+x+8=180; 4x+10=180; 4x=170; x= 170/4= 42.5
Angle on top is x+8=42.5+8=50.8
Angle on the bottom is 3x+2=3•42.5+2= 129.5
Your answer would be 50.24
