Answer: A proportional relationship needs to pass through the origin and have a linear (straight) slope. Let me know if you need more specifics.
Answer: The area is 201.06
It's a hexagon.
The formula of the sum of internal angles in the polygon:

Step-by-step explanation:
<u>Step 1: Define</u>
We are given a 5-sided polygon (irregular pentagon)
n = 5
<u>Step 2: Find Sum</u>
- Substitute in <em>n</em> [Sum of Angles]: 180(5 - 2)°
- (Parenthesis) Subtract: 180(3)°
- Multiply: 540°
