Answer:
3x+30= 116° 2x=64°
Step-by-step explanation:
the angle below 2x is the same as 3x+20 so we know that 5x+20=180 so solve this
5x+20=180
5x=160
x=32
sub x into the angle equations
3(32)+20=116
2(32)=64
 
        
                    
             
        
        
        
The prefix in the word "regroup" is "re" and it means "again". Separate the words like this (re)read to find the "prefix" 
Just think when your teacher ask you to reread the book or the problem.It should come to mind as "Read again" 
Good Luck!
