Briefly explain, in your own words, the sides that are found in a kite.

Well, in MY own words, a kite has four sides.  It has two pairs of sides. Each pair consists of two sides of the same length that meet.

Where the pairs meet, are two equal angles.

If you draw straight lines from the corners right across, the intersections of the straight lines will be right angles.

For this case we have the following equation:

We must clear the value of the variable "x" as a function of r, s and t:

If we multiply by "r" on both sides of the equation we have:

If we subtract "t" on both sides of the equation we have:

If we divide by "2" on both sides of the equation we have:

Thus, the value of the variable "x" is:
