Two poles of heights 9 in and 17m stand on a plane ground. If the distance between their feet is 15 m, then the distance between their tops is:
A)15 m
B)16 m
C)17 m
D)18 m
Correct Answer:
C
Solution :
Let AB & MN are two poles of height 9 in and 17m respectively \[\therefore \] AP= BN- 15 cm MP = 17 - 9 = 8m \[\therefore \] Distance between their tops = \[\sqrt{M{{P}^{2}}+A{{P}^{2}}}=\sqrt{{{8}^{2}}+{{15}^{2}}}\] = \[\sqrt{289}=\]
