Answer:
Step-by-step explanation:
Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180 
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
Therefore 
Angle A =67 degrees
Angle B= 94 degrees 
Angle C = 19 degrees 
 
        
             
        
        
        
Answer: (-2y+3)(y+11) 
Step-by-step explanation:
33 is 3×11 so expect something like 
(y+3)(y+11) = y^2+14y+33
leading term has coefficient -2 so
one factor is like (-2y+__)
Try (-2y+3)(y+11) = -2y^2-19y+33
which happens to be the answer
