I DONT GET THISSS ( The lesson that I am learning is vertical angles)

Find the value of each variable

The equation respenting the left table is

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
