two point A and B are each distance 2000m from a third point C with an elevation of 100m, from which the measure vertical angle to A is 3.5 degrees B is 1.5 degrees. what is the difference in elevation between A and B considering the effects of earth curvature and refraction?

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
