Step-by-step explanation:
Apply the law of cosines. and solve for A

A = 79.04239272, or 79
The range of the function is 
Explanation:
The function is 
The domain of the function is 
We need to find the range of the function.
The range can be determined by substituting the values of domain in the function.
Thus, the range of the function when the domain is -3 is given by



Thus, the range is -19 when 
The range of the function when the domain is 0 is given by



Thus, the range is -4 when 
The range of the function when the domain is 4 is given by



Thus, the range is 16 when 
Thus, the range of the function is
when their corresponding domain is 
Arranging the range in order from least to greatest is given by

Hence, the range of the function is 
The vertex form is y=(x-4)^2-1
