Sammy used the diagram to compute the distance from Ferris, to Dunlap, to Butte. How much shorter is the distance directly from Ferris to Butte than the distance Sammy found? Round to the nearest mile. Ferris 15 miles Dunlap Butte 20 miles

Answer :

Applying the Pythagorean theorem

[tex]\begin{gathered} x^2=15^2+20^2 \\ x^2=225+400 \\ x^2=625 \\ x=\sqrt[]{625} \\ x=25 \end{gathered}[/tex]

Short distance is 35-25=10
