Answer:
x + 6x+10   + x+2 = 180
x = 21
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x + 6x+10   + x+2 = 180
Combine like terms
8x + 12 = 180
Subtract 12 from each side
8x+12-12 = 180-12
8x =168
Divide each side by 8
8x/8 = 168/8
x =21
 
        
                    
             
        
        
        
X + 100 = 4x +49 
x= 17
158+148+32+x = 360
338+x= 360
x= 22
