Answer:
22.15
Step-by-step explanation:
So, lets go over a few things:
The y coordinates is the Foot length.
The x coordinate is the Arm span.
They gave us a yellow stone in the graph, this shows what the feet length is when the arm length is at a specific value.
So we need to find the foot length when the arm length is at 160.
Once you have pinpointed 160 on the graph, go strait up until you get to the yellow line.
WHen you hit the yellow line, look at the y axis. It should seem to be in between 21 and 23.The only answer in between 21 and 23 is 22.15
So this is the answer!
Hope this helps! :D
