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

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 125, 25
Igoryamba

Answer:

Given sequence is an arithmetic sequence.

Step-by-step explanation:

Given sequence is:

125, 25, 5, .. ..​

Here

a_1 = 125\\a_2 = 25\\a_3 = 5

  • 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

r = \frac{a_2}{a_1} = \frac{125}{25} = 5\\r = \frac{a_3}{a_2} = \frac{25}{5} = 5

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