Answer:   1. ∠A= 80.75°  2. 41.79 
Step-by-step explanation:
Since, According to the sines low,

Here, CB= 4.1 cm,  AB = 3.3 and ∠ C = 52.6°

⇒ 
⇒  
⇒ A = 80.75° 
2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1
=34.86 + 6.93
= 41.79 square cm

Answer:
Approximately $14.20
Step-by-step explanation:
Let the cost of the groceries be represented by c, then;
cost price + VAT = c + (5% of c) 
To get the value of the cost, c, that would make him spend as close to $15. Since the tax is 5% of the cost price, then the cost price would be close to $15.
Let c = $14.20, then;
So that,
c + (5% of c) = 14.20 + (5% of 14.20)
                     = 14.20 + 0.71
                     = $14.91
Thus, the greatest total cost of groceries Darla can spend in order to spend as close to $15 as possible is approximately $14.20.
 
        
             
        
        
        
Answer:
Option A)

Step-by-step explanation:
We are given the following in the question:
V varies jointly as h and the fifth power of r.

Combing the two equations, we get,

Now, removing the sign of proportionality and adding the constant of proportionality, we get,

where k is the constant of proportionality.
Thus, the correct answer is 
Option A)
