Answer: x = -4 or x = 7
Step-by-step explanation:
x^2 - 3x - 28 =/>
 (factor) 
(x^2 + 4)(x-7) = 0 
x + 4 = 0 or x - 7 = 0 
(subtract -4 from 0 and 7 from 0)
x = -4 or x =7
 
        
             
        
        
        
Following the principle of supplements angles, the angle next to the 101 is 79°. 79+38+c(call the third angle c) = 180
c = 180-117 =63° x is supplemental to c so 180 = x +c 
180=x + 63 
x =117
