Answer:
Two systems of equations are equivalent if they have the same solution(s).
Geometric sequences go up due to a common ratio. Here the common ratio can be worked out by dividing a term by its previous term e.g term 2 divided by term 1.

Therefore the common ratio is 6.
x=84
Add up all the sides and then subtract that number by the original amount of degrees. 540
