A) \[30{}^\circ \]
B) \[75{}^\circ \]
C) \[60{}^\circ \]
D) \[45{}^\circ \]
Correct Answer: D
Solution :
Let \[AB=h\] be the pole and let \[\angle ACB=\theta \] Let AC be the shadow Hence, by hypothesis, \[CA=h\] From right angled \[\Delta \,BCA,\] \[\tan \theta =\frac{h}{h}=1\] \[\therefore \] \[\theta ={{45}^{o}}\]You need to login to perform this action.
