Answer:
Step-by-step explanation:
Given: 
RUTS is a rectangle.
To prove:
∠USR ≅ ∠SUT
                   Statements                            Reasons
1. RUTS is a rectangle                   1. Given
2. RU = ST, UT = RS                      2. By the definition of a rectangle
3. ∠STU = ∠SRU = 90°                  3. Definition of a rectangle
4. ΔURS ≅ ΔSTU                           4. By the LL theorem of congruence
5. ∠USR ≅ ∠SUT                           5. CPCTC 
 
        
                    
             
        
        
        
The greatest common factor of 10 and 20 is 10.

Answer: 625</h3>
Work Shown: 
The set {A,B,C,1,2} has five items. There are four slots to fill. 
So we have 5^4 = 5*5*5*5 = 625 different possible passwords where the characters can be repeated.
 
        
        
        
29% would be the answer if you are rounding up
