To find the longest possible perimeter of the triangle, we need to consider the triangle with its two given angles and one side length of 7.

The sum of the angles in a triangle is always ( \pi ) radians (or 180 degrees).

So, if we subtract the given angles from ( \pi ), we get the measure of the third angle.

( \pi - \frac{3\pi}{8} - \frac{\pi}{2} = \pi - \frac{3\pi}{8} - \frac{4\pi}{8} = \pi - \frac{7\pi}{8} )

Now, we know the measure of all three angles of the triangle.

Using the Law of Sines, we can find the lengths of the other two sides of the triangle.

Then, we can calculate the perimeter of the triangle by adding all three side lengths together.

Finally, we can maximize the perimeter by maximizing the lengths of the other two sides of the triangle.

Thus, the longest possible perimeter of the triangle can be calculated accordingly.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
