- Sum of Angles: 180(n - 2)
Step-by-step explanation:
<u>Step 1: Define</u>
Number of sides <em>n</em> = 10
<u>Step 2: Find</u>
- Substitute: 180(10 - 2)
- Subtract: 180(8)
- Multiply: 1440°
<u>Step 3: Find 1 angle</u>
<em>We have 10 sides.</em>
- Divide: 1440/10 = 144
5y = 135....divide both sides by 5
y = 135 / 5
y = 27 <==
