Answer:
Jason is 14 year old.
Step-by-step explanation:
Given: Joe, John and Jason are each a year apart in age.
Sum of their age is 39.
Lets assume the age of Joe be x
∴ Age of Jahn will be
And age of Jason will be
Now, putting up an equation for the sum of their age.
∴
Opening the parenthesis.
⇒
⇒
Subtracting both side by 3
⇒
Dividing both side by 3
⇒
∴
Hence, Joe is 12 year old.
Next subtituting the value of x to find age of Jason and John.
Jason=
∴Jason= 14 years.
John age=
∴ John Age= 13 years.
Hence, Jason is 14 year of age.

Okay, take a look at diagram 1 (I know it's rubbish I did it on paint :D), this shows all the information you've given in the question. The two coordinates and the distance between them.
Now if we draw additional lines on this diagram, we can make a right-angled triangle (this is on diagram 2). We can also work out the lengths of the additional sides because we know both coordinates at the end-points of the additional lines.
Finally because this is a right-angled triangle, Pythagoras' theorem must apply to its sides meaning
therefore x=5.
