Option A, The shipping cost is a function of the weight of the package.

Step-by-step explanation:

Since the weight of the package differs, it is not the function.  The shipping cost is the function while the weight is the variable.

 Option A, The shipping cost is a function of the weight of the package.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
