$16.$The law of cosines is a statement about a general triangle that relates the lengths of its sides

to the cosine of one of its angles. Such that for the triangle below:

$A^2=B^2+C^2-2BCcos()$

Write a program that takes the values of angle $$ and the lengths

of $B$ and $C.$ These input values are passed by reference to a

function findA using their memory addresses. This function

calculates and returns the length of $A.$ The calculated length of $A$

should then be displayed on the screen.

Note the following:

Ensure that the values for angle $$ and the lengths of B and C taken from the user are

always positive $($unsigned$)$ integers.

Ensure that the sum of the of values for $$ taken from the user is less than or equal to

$90$

Remember that the $sin(),cos()$ and $tan()$ functions are available in the math.h file

Remember that the sqrt$()$ and pow$()$ functions are available in the math.h file
