I got 180 because (although the picture is smaller and digital meaning I may be off) angle AOD = 85 degrees while angle BOC = 95. 95 + 85 = 180.
        
                    
             
        
        
        
Answer:
the answer is 2,and 4 and 5
 
        
             
        
        
        
(x^m) times (x^n)=x^(m+n)
(1/8)^5 times (1/8)^3=(1/8)^(5+3)=(1/8)^8=1/(8^8)
        
             
        
        
        
2/3 divided by 1/2 equals 3/4.
So your answer would be 1/2.
