Answer:

• from pythogras theorem:


{ \rm{ {c}^(2) = {a}^(2) + {b}^(2) }} \\

a → 5 km

c → 8 km


{ \tt{ {8}^(2) = {5}^(2) + {b}^(2) }} \\ \\ { \tt{ {b}^(2) = {8}^(2) - {5}^(2) }} \\ \\ { \tt{ {b}^(2) = 39}} \\ \\ { \tt{ \: b = √(39) = 6.2 \: km }}

Applying pythagorean theorem:-


\\ \sf\longmapsto 8^2-5^2=b^2


\\ \sf\longmapsto 64-25=b^2


\\ \sf\longmapsto b^2=39


\\ \sf\longmapsto b=√(39)


\\ \sf\longmapsto b=6.24
