2 would most like be doubled and be 4 I think...
        
             
        
        
        
To find out how many brothers they have, they need to multiply 4×1= 4 
So there are 4 brothers.
I hope this helped :)

Answer:
AC = 3.72 units
Angles:
A = 132.6°
C = 27.4°
Step-by-step explanation:
AC² = 5² + 8² - 2(5)(8)cos(20)
AC² = 13.82459034
AC = 3.718143399
3.718143399/sin20 = 8/sinA 
sinA = 0.7358944647
A = 180 - 47.38285134
A = 132.6171487
3.718143399/sin20 = 5/sinC
sinC = 0.4599340405
C = 27.38285134 
 
        
             
        
        
        
I think the answer is negative 8 square root 726 
then the answer if I am right sorry if I am not would be negative 88 square root 6
again sorry if wrong
