A) 16 m
B) 25 m
C) 50 m
D) None of these
Correct Answer: B
Solution :
Let OP be the clock tower standing at the midpoint\[O\]of side BC of\[\Delta ABC\]. Let\[\alpha =\angle PAO\]\[=co{{t}^{-1}}3.2\]and\[\beta =\angle PBO=\cos e{{c}^{-1}}2.6.\] Then,\[cot\text{ }\alpha =3.2\]and \[cosec\text{ }\beta =2.6\]. \[\therefore \]\[\cot \beta =\sqrt{\cos e{{c}^{2}}\beta -1}=\sqrt{{{(2.6)}^{2}}-1}=2.4\] In a triangle PAO and PBO, we haveYou need to login to perform this action.
