6 can go into 59, nine times. Therefore 9 times 6 equals 54
We are given the first term and the common ratio, this means they belong to a geometric series.
For the given series:

Each term of the geometric series is obtained by multiplying the previous term by common ratio.
So the next terms will be:
-4.5, -6.75, -10.125, -15.1875, -22.78125
The general formula for the G.P would be:

On plotting the series, the result will be like this:
You are correct. The answer is B.) They are congruent because they are corresponding angles.
Nice job! Hope this helped :)
