Answer:
y + 7.8 = 25.2
y = 17.4
Step-by-step explanation:
y + 7.8 = 25.2
(now we solve the equation .... we substract 7.8 from each side of the equation )
y = 25.2 - 7.8
y = 17.4

sorry if im wrong.
Answer:
If I'm correct I think 4 is the polygon
Well you can start by drawing a triangle with the information
the size of angle B can be found using the Law of Sine
![\frac{sin(150)}{9.4)} = \frac{sin(B)}{4.8}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bsin%28150%29%7D%7B9.4%29%7D%20%20%3D%20%20%5Cfrac%7Bsin%28B%29%7D%7B4.8%7D%20)
the size of angle C can be found using angle sum of a triangle.
The length of side c can be found using the Law of Cosines
![c^2 = 4.8^2 + 9.4^2 - 2 \times4.8\times9.4\times cos(C)](https://tex.z-dn.net/?f=c%5E2%20%3D%204.8%5E2%20%2B%209.4%5E2%20-%202%20%5Ctimes4.8%5Ctimes9.4%5Ctimes%20%20cos%28C%29)
hope it helps
