Nivedita stops to walk after covering a distance of 10 km to the west. She then turns to the right and walks 8 km. Again she walks 4 km to the right. How far is she from her office?
A) 18 km
B) 8 km
C) 16 km
D) 10 km
Correct Answer:
D
Solution :
OS =10 KM, RS = PQ = 8 km RP = SQ = 4 km \[\therefore \]\[\,OQ=1=-4=6\,\,km\] From\[\Delta OPQ\] \[\,PO=\sqrt{{{6}^{2}}+{{8}^{2}}}\] \[=\sqrt{36+64}=\sqrt{100}=10\]
