Answer:
39.50
42.50
Step-by-step explanation:
Age of the 2 men = sum of the ages of the 6 men - sum of the ages of the 4 men 
 Average = sum of ages / total number of men
35 = sum of ages / 6 
sum of ages = 35 x6 = 210
32 = sum of ages / 4 
32 x 4 = sum of ages 
128 
210 - 128 = 82
age of the younger man = x 
age of the older man = 3 + x 
x + 3 + x = 82
2x + 3 = 82
2x = 82 - 3 
2x = 79
x = 79/2 = 39.5
older man = 39.5 + 3 = 42.50
 
        
             
        
        
        
Answer:
sin A = 13/85
Step-by-step explanation:
Opposite Angle A is side BC, of length 13.  The length of the hypotenuse is 85.  The sine function is defined as the ratio opp/hyp.  In this problem that ratio is 
opp
------ = sin A = 13/85
 hyp
We use the inverse sine function arcsin x to determine Angle A:
A = arcsin 13/85 = 8.8 degrees
