3.14 on the length. but if you add to a graph send another one to my comment and show me
explanation
In order for two lines to be perpendicular, their slopes must multiply together to equal to negative one
So we do negative one divided by 2/5 to get the slope of the red line
Which is -5/2
To check, we do 2/5 multiplied by -5/2 which equals to -1 so our answer is correct
Answer: 178 4/5 or as an improper fraction 894/5
