Answer:

Step-by-step explanation:
The only thing important in this question in the original equation is the slope, which is 3, the multiplyer for x. To find the opposite slope follow the steps below.
The first step is to make the original slope into a fraction.

Then flip the numerator and denominator.

Now multiply this value by -1.

There is the opposite slope of 3.
I think the answer is c 30 degrees!!
With all the given context, I would assume it’s length times width, which would give us an answer of 40 :) hope this helped !
It would actually be no solutions, since an equation can't have more than one equal sign xD
