Answer 1

Answer: 6 km

Step-by-step explanation:

Using the Pythagoras theorem .

(10)^2=(8)^2+(x)^2

100=64+(x)^2

36=(x)^2

x=6 km

Answer 2

Answer: 6 km

Step-by-step explanation:

As he goes 10 km South-East and then moves 8 km towards west

10 km is the hypotenuse of the right-angled triangle formed

8 km represents the side of the right-angled triangle formed

Therefore, by Pythagoras theorem

(Another side)^2=(10)^2-(8)^2

=100-64

=36

Hence,

Another side=√36

=6km
