Question

Help me on this please

Answer 1

Answer:

5 miles.

Step-by-step explanation:

The Pythagorean theorem $a^{2}+b^{2} =c^{2}$ will find any side length of a perpendicular triangle when two sides are known.

We substitute for a, the shortest side, a=3 and for b, the longer side, b=4 to find the slanted hypotenuse c.

$a^{2}+b^{2} =c^{2} \\3^{2}+4^{2} =c^{2} \\9+16=c^{2}\\25=c^{2}\\5=c$

The direct route is 5 miles.
