Even more algebra because why not [last ones for today]

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
