Answer:
X=128°
Step-by-step explanation:
Because an exterior angle of a triangle is equal to of the two opposite interior angle.
The sum of the exterior and interior angle is equal to 180° 
In this case the part marked red = 90° because is a right angled triangle. 
90+38=128 
180- 128=52
180- 52=128
x=128. 
 
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
Using the coefficients of each term and evaluating for h = - 4
- 4 | 1   - 7   - 7   20
       ↓   - 4   44   - 148
      ---------------------------
       1   - 11   37   - 128 ← remainder
Quotient = x² - 11x + 37 , R - 128
