Answer:
x=145°
Step-by-step explanation:
180 = 35 + x
x = 180-35
x= 145°
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:
Answer:

Answer:

Step-by-step explanation:
using form:

where a: starting number
where r: common ratio (in this case each next term is 3 times previous term)
