It is an irregular regular polygon, called a nonagon as the shape has unequal length sides and angles. lol
Answer:
x = 23
Step-by-step explanation:
Exterior angles equals the sum of opposite interior angles.
2x+ 3 + 51 = 100
Combine like terms.
2x + 54 = 100 {Subtract 54 from both sides}
2x = 100 - 54
2x = 46 {Divide both sides by 2}
x = 46/2
x = 23
<u>Given</u>:
The perimeter of a polygon is the sum of the lengths of the sides of the polygon.
Given that the sides of the polygon are x + 1, 3x - 2, 3x - 2, x + 1.
We need to determine the perimeter of the polygon.
<u>Perimeter of the polygon:</u>
The perimeter of the polygon can be determined by adding the lengths of the sides of the polygon.
Thus, we have;

Removing the parenthesis, we get;

Adding the like terms, we get;

Thus, the perimeter of the polygon is 
Step-by-step explanation:
5. <1 + <8 = 180degree
6. we have <1 = 24(your id number)
24+ <8 = 180
<8=180-24
<8 = 156
7. <1 = <5
8. <5 = 24
