Cos(theta)=a/h
Cos(theta)=12/13
Theta=cos^-1(12/13)
Theta=22.62 degrees

Answer:
AC < BC < AB
Step-by-step explanation:
Given: BC = 118
AB = 63*2 = 126
AC = 360 - (BC+AB)
AC = 360 - (118+126) = 116
 
        
             
        
        
        
Answer:
R 694.4
Explanation:
simple interest = 
 → 
 → R 134.4
where p refers to principal, r refers to rate, t refers to time.
total money: 
invested money + simple interest
R 134.4 + R 560 → R 694.4
 
        
                    
             
        
        
        
So close! But instead of adding the multiplication sign after the number you need to add them before. Good job though! :)
