Answer:
180=2x+ 24( angles opposite to equal sides)
156/2=x
x=78
Step-by-step explanation:
Answer:

Step-by-step explanation:
Given function is
.
Now we need to make a table of values for the function rule then graph the function.
We are free to plug any values of x like -3,-2,-1,0,1,2,3,... etc becaues domain of polynomial function is all real numbers.
Let's plug x=1 into given function to find the y-value
![y=-x^2+4](https://tex.z-dn.net/?f=y%3D-x%5E2%2B4)
![y=-(1)^2+4](https://tex.z-dn.net/?f=y%3D-%281%29%5E2%2B4)
![y=-1+4](https://tex.z-dn.net/?f=y%3D-1%2B4)
![y=3](https://tex.z-dn.net/?f=y%3D3)
Hence the first point is (1,3).
Same way we can find few more points to complete the table then graph those points and connect them to get the final graph.
