Explain how you would find the coordinates of the image
of (5.2) if it was reflected over the x-axis and then that
image was reflected over the y-axis. what would be the
end result?

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

$25 becasue a 10 increase would make it from 80 to 50
