so that is the common ratio.
Answer:
Ok here
Step-by-step explanation:
The answer is 19
work :
1-multiply the numbers by a submultiple of 10 to remove the decimal points.

2-

note: there is no need to get it back to decimal number unless you multiply just one of the numbers or multiply the numbers with different submultiples of 10
good luck
Answer:
Step-by-step explanation:
<u>Property of regular polygons:</u>
- Sum of Interior Angles = (n−2) × 180°, where n is number of sides
<u>In our case we have:</u>
- 158.8×n = (n - 2)×180
- 180n - 158.8n = 360
- 21.2n = 360
- n = 360/21.2
- n = 17
