Answer:
The value of w is 7.
Step-by-step explanation:
According to Pythagoras theorem,
Hypotenuse²=Perpendicular²+Base²
H²=P²+B²
Here, 
Hypotenuse given=7√2
w=y
Perpendicular=Base=x
(7√2)²=x²+x²
49*2=2x²
(49*2)/2=x²
49=x²
√49=x
7=x
Perpendicular=x=7
 
        
             
        
        
        
Answer:
 C.) n < 6
Step-by-step explanation:
Subtract 8:
 n/-3 > -2
Multiply by -3. The negative multiplier requires the comparison be reversed:
 n < 6
