Answer:
37 degrees because of similarity
Step-by-step explanation:
you can see the distance between the intervals in the graph more easily because you can see how far the plots are away from each other by connecting the w/ lines. Ex you had 5 on a graph and you had 12 after it there is an interval of 8 in between so you can visually see how far apart the numbers area simple 2d xy line graph has only the possibility for 2 different variables (x and y).. for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs. Hope this helps.
