Your answer is 14/5. hope that helps :)
Answer:
1 and 3 is right and I’m pretty sure 2 is right also.
Step-by-step explanation:
The answer to this question is 8/10 which also equals 4/5
To find conjecture about regular polygon, use the formula
![\frac{360}{n}](https://tex.z-dn.net/?f=%20%5Cfrac%7B360%7D%7Bn%7D%20)
Where, n = number of sides of the regular polygone
1) Triangle
n =3
So, Conjecture of the triangle =
![\frac{360}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B360%7D%7B3%7D%20)
= 120
2) Square
n =4
So, Conjecture of the square =
![\frac{360}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B360%7D%7B4%7D%20)
= 90
3) Pentagone
n = 5
So, Conjecture of the pentagon =
![\frac{360}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B360%7D%7B5%7D%20)
= 72
4) Hexagone
n = 6
So, Conjecture of the pentagon =
![\frac{360}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B360%7D%7B6%7D%20)
= 60.
