Answer:
x = 126°
x - 30 = 96°
Step-by-step explanation:
The sum of angles in a 5 sided polygon is 540°.
Hence all these angles would = 540
x + x + (x - 30) + (x - 30) + (x - 30) = 540
Collect like terms
5x - 90 = 540
Rearrange
5x = 540 + 90
5x = 630
x = 126
x - 30 = 96

Answer:
Given sequence is an arithmetic sequence.
Step-by-step explanation:
Given sequence is:
125, 25, 5, .. ..
Here

- A sequence is geometric sequence when the common ratio of consecutive terms is same. It is denoted by r.
- A sequence is an arithmetic sequence when the common difference of consecutive terms is same. It is denoted by d.
Finding the common ratio

As we can see that the common ratio is same, the given sequence is a geometric sequence.
