Step-by-step explanation:
To find:
How far is the man from the starting point?
( Refer to the given attachment. )
The man started from the point A and reached the point B, then to point C, D and lastly to E.
Here, AB = 12 km, BC = 6 km, CD = 3 km, DE = 6 km.
We have to find: AE = ? km
We join E, F and F, A.
Here, CD + EF = AB
⇾ 3 + EF = 12
⇾ EF = 9
∴ EF = 9 km
Again, AF = DE + BC
⇾ AF = 6 + 6
⇾ AF = 12
∴ AF = 12 km
Now, since AFE is a right-angled triangle, we write;
EF² + AF² = AE²
⇾ AE² = 9² + 12²
⇾ AE² = 81 + 144
⇾ AE² = 225
⇾ AE² = 15²
⇾ AE = 15
∴ AE = 15 km
Answer:
