Answer:
1)
2)
Step-by-step explanation:
Assuming that our function is for the first case and for the second case.
Part 1
We can rewrite the expression like this:
And we can reorder the terms like this:
Now if we apply integral in both sides we got:
And after do the integrals we got:
Now we can use the initial condition
And the final solution would be:
Part 2
We can rewrite the expression like this:
And we can reorder the terms like this:
Now if we apply integral in both sides we got:
And after do the integrals we got:
Now we can use the initial condition
And the final solution would be:

a line of symmetry will connect a vertex and a midpoint of an opposite side
it has 7-fold symmetry.
<u><em>Explanation</em></u><span><u><em>: </em></u>
A line of symmetry is a line that we can use to <u>"fold"</u> a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex.
Since there are 7 vertices, there will be 7 lines of reflection.</span></span>
