If you stood at sea level, the base of the hawaiian volcano mauna kea would be at the bottom of the ocean, at 19,680 feet below you. the top would be 33,476 feet above the base. write a numerical expression you can evaluate to find the elevation of the top of mauna kea above sea level. then find the elevation.

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?
