Hi there,
Properties of Equality is two equations that have the same solution which are called equivalent equations. For example: 5+3=2+6 which all equal to 8.
In geometry, properties of Equality are the reflexive (2x=2x, a=a, b+1=b+1), symmetric (2a=3b then 3b=2a) and transitive property (if a+1=3 and 3=1-b, then a+1=1-b)
Hope this helped :)
Have a great day 
 
        
             
        
        
        
Answer:
x=2
Step-by-step explanation:
2x+4=4x 
-2x     -2x  
4=2x/2x 
4/2=x 
x=2

Answer:
∠ XZY ≈ 23.6°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin Z =  =
 =  =
 =  , thus
, thus
Z =  (
( ) ≈ 23.6° ( to 1 dec. place )
) ≈ 23.6° ( to 1 dec. place )
 
        
                    
             
        
        
        
567 / 18 = 31.5
