A) \[\frac{a+b}{a-b}\]
B) \[\frac{a-b}{a+b}\]
C) \[\sqrt{ab}\]
D) \[{{(ab)}^{1/3}}\]
Correct Answer: C
Solution :
Let there are two points C and D on horizontal line passing from point B of the base of the tower AB. The distance of these points are b and a from B respectively. \[\therefore BD=a\,\,\text{and}\,\,BC=b\]. \[\because \] line CD, on the top of tower A subtends an angle \[\theta \], \[\therefore \,\,\angle CAD=\theta \]You need to login to perform this action.
