- Sum of Angles: 180(n - 2)°
Step-by-step explanation:
<u>Step 1: Identify</u>
We have an irregular hexagon. We have n = 6 sides.
<u>Step 2: Find Angle Sum</u>
- Substitute in <em>n </em>[SA]: 180(6 - 2)°
- (Parenthesis) Subtract: 180(4)°
- Multiply: 720°
X-5 + 5x-12 = 25
combine like terms
6x-17 = 25
add 17
25 + 17 =42
6x + 42
x = 7
