João and Pedro are in a park observing a tree that has two branches coming out of the trunk at different angles, forming an angle between them. João and Pedro start walking away from the tree trunk, each one towards one of the branches, so that Pedro is 40 degrees to the left of João's path. Knowing that, at the point where the tree branches are, there is an angle between the branches of 20 degrees, calculate the exterior eccentric angle between João's path and Pedro's path. Additionally, show the step-by-step process to solve the question.

In a circumference, from an external point P, two intersecting lines are drawn that intersect the circumference at points D and G by the first line, with G being the farthest point from P, and at points E and F by the second line, with F being the farthest point from P. Knowing that the arc GF measures 130º and the arc DE measures 50º, what is the measure of the angle formed by the lines?

In a fictional city, there is a circular square with a monument in the center. A curious tourist decided to measure the distances using a drone. He noticed that there are two points, A and B, from which the tangent lines to the square intersect the monument, forming a 90° angle. Knowing that the distance from point A to the center of the square is 20m and the distance from point B to the center of the square is 15m, calculate: 1) The power of points A and B in relation to the square. 2) The distance between points A and B.
