Answer: x+2 / x+ 9, x = -2, x=-9   ( A )
Solution:
Breakdown the problem into two sets 
Step 1:  simplify  x^2 -10x - 24
Factorize the above equation,
Multiply the last term (24) with the first term coefficient i.e. 1
Step 2: Then, find the factors of 24 in a way that when you add or subtract it sums up to 10
 x2 - 12x + 2x - 24  >>>>  (x2-12x) + (2x-24) >>> take common 
>>>> x(x-12) + 2( x-12)
Step 3:   (x + 2)  (x - 12) 
Step 4: Step 1:  simplify x^2 - 3x - 108 using the same steps
x2 - 12x + 9x - 108 >>>>  take common x(x-12) + 9 ( x -12) >>>
 (x + 9)  (x - 12) final product 
Now, Simplify the equation as a whole
  (x + 2)  (x - 12) /  (x + 9)  (x - 12)                         Note:  (x - 12) cancels out   
=  (x + 2) /  (x + 9)     with x= -2 and x= -9
 
        
             
        
        
        
Answer:
x=56 and the exterior angle is 116
Step-by-step explanation:
We will call the unknown angle in the triangle y.  Angle y and the angle (2x +4) form a straight line so they make 180 degrees.
y + 2x+4 =180
Solve for y by subtracting 2x+4 from each side.
 y + 2x+4 - (2x+4) =180 - (2x+4)
y = 180-2x-4
y = 176-2x
The three angles of a triangle add to 180 degrees
x+ y+ 60 = 180
x+ (176-2x)+60 = 180
Combine like terms
-x +236=180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Multiply each side by -1
-1*-x = -56*-1
x=56
The exterior angle is 2x+4.  Substitute x=56 into the equation.
2(56)+4
112+4
116
