Answer:
- arc BF = 76°
- ∠M = 31°
- ∠BGE = 121°
- ∠MFB = 111°
Step-by-step explanation:
(a) ∠FBM is the complement of ∠FBC, so is ...
   ∠FBM = 90° -52° = 38°
The measure of arc BF is twice this angle, so is ...
   arc BF = 2∠FBM = 2(38°)
   arc BF = 76°
__
(b) ∠M is half the difference between the measures of arcs BE and BF, so is ...
   ∠M = (1/2)(138° -76°) = 62°/2
   ∠M = 31°
__
(c) arc FC is the supplement to arc BF, so has measure ...
   arc FC = 180° -arc BF = 180° -76° = 104°
∠BGE is half the sum of arcs BE and FC, so is ...
   ∠BGE = (1/2)(arc BE +arc FC) = (138° +104°)/2
   ∠BGE = 121°
__
(d) ∠MFB is the remaining angle in ∆MFB, so has measure ...
   ∠MFB = 180° -∠M -∠FBM = 180° -31° -38°
   ∠MFB = 111°
 
        
             
        
        
        
2(x+1)=2x+2  if you factor the right side ..
2(x+1)=2(x+1)
This is always true for any value of x so there are infinitely many solutions...
x= all real numbers.
