B, because thats 50 grams either direction of the given weight.
        
                    
             
        
        
        
Answer:
a = 4.949
b = 4.949
c = 7
Step-by-step explanation:
c ( hypothenuse ) = 7
to find a, use sine
Sine = 
Sine 45 = 
sine of 45 is 0.707
0.707 = 
multiplt 7 on both sides:
0.707 x 7 =  x 7
 x 7 
a = 4.949
to find b, use cosine
Cosine = 
Cos 45 = 
cos of 45 is 0.707
0.707 = 
multiply 7 on both sides:
0.707 x 7 =  x 7
 x 7 
b = 4.949

<h3>35.</h3>
Step-by-step explanation:
To find the number of girls in the class we must first find the total parts
That's
2 + 7 = 9
In the ratio 7 correspond to girls so the number of girls in the class are
7/9 × 45
= 7 × 5
= 35
