Answer: 1, 3, and 4 can form triangles. The rest can not.
Step-by-step explanation:
on triangles 1, 3, and 4, the 2 smaller sides added together are greater than the longer side.
 
        
                    
             
        
        
        
He could be 40321 years old. 
If you divide 40321 by any odd or even number between 1 and 9, the remainder is 1. 
I got this number by doing (2*3*4*5*6*7*8) + 1

Answer:
1. = 99 degrees   2. = 85 degrees 
Step-by-step explanation: All quadrilaterals have a total of 360 degrees. You can figure out the rest.
 
        
                    
             
        
        
        
The 3 angles of a triangle equal 180.
Subtract the bottom 2 angles from 180 and you get 50
So 8x + 2 = 50
Subtract 2 from both sides:
8x = 48
Divide both sides by 8
X = 6
