Answer:
a = 4
b = 4
Step-by-step explanation:
This is a special right triangle with angle measures of 45° 45° 90° and side lengths x x x√2
 
        
             
        
        
        
Answer:
8.4 x 10^10 in scientifif notation is the same, in regular its 84000000000
3 x 10^7 in scientific notation is the same and in regular its 30000000
 
        
                    
             
        
        
        
Length = √(y2-y1)² + (x2-x1)²
l = √(5 - 5)² + (9 + 2)²
l = √0² + 11²
l = √121
l = 11
In short, Your Answer would be 11 units
Hope this helps!
