S= a/4 + 8u
S - 8u = a/4 (First you subtract 8u from both sides)
4(S - 8u) = a ( Then you multiply both sides by 4)
Final answer:
4(S - 8u) = a
        
             
        
        
        
Answer:
Before this problem gets  an answer, can you define "gotta." Does this work mean  isosceles? 
Step-by-step explanation:
 
        
                    
             
        
        
        
If they are supplementary then 3x + 17x = 180
20x = 180
x = 9     
m<GHI = 27 degrees
m < LMN = 153 degrees
