Short cut

Imagine that you are going to a friend. That path has a length 120 meters. Then turn doprava and go other 630 meters, and you are at a friend's.

The question is, how much will the journey be shorter if you go direct across the field?

Correct answer:

x =  108.7 m

Step-by-step explanation:

a=120 m b=630 m  c0=a+b=120+630=750 m  c12=a2+b2  c1=a2+b2=1202+6302=30 457 m641.3267 m  x=c0c1=750641.3267=108.7 m
