Answer:
66 
Step-by-step explanation:
EHG is a straight line so it is 180°. 
You already know the value of FHG, so you can find the value of 2x. 
180° = 48° + 2x 
2x = 180° - 48° 
     = 132 
x = 132° ÷ 2 
   = 66 
 
        
                    
             
        
        
        
Answer:
98
Step-by-step explanation:
Mathematically, when we add all the angles of a triangle, we get 180
Thus;
x + 1 + 2x-2+ 3x-5 = 180
6x-6 = 180
6x = 186
x = 186/6
x = 31 
so the measure of the biggest angle is 3x -5 
= 3(31) + 5 = 93 + 5 = 98
 
        
             
        
        
        
Answer:
Not a factor
Step-by-step explanation:
We can use Factor Theorem to answer this question. According to this theorem, in order to find if (x - a) is a factor of a polynomial f(x), calculate f(a). If f(a) comes out to be equal to zero, this will mean that (x-a) is  factor of f(x).
Here, the expression we have is (x + 7), so we need to find f(-7) in order to check if (x+7) is a factor of f(x) or not

Substituting x = -7, we get:

Since f(-7) ≠ 0, (x + 7) is not a factor of the polynomial f(x)
