If a pole 24 metre height cast a shadow of 8 V3 metre long on the ground, then the sun's angle of elevation at that instant is -
A) \[30{}^\circ \]
B) \[60{}^\circ \]
C) \[45{}^\circ \]
D) \[90{}^\circ \]
Correct Answer:
B
Solution :
Let AB is the height of pole and BC is the length of shadow. \[\therefore \,\,\,\,\tan \theta =\frac{AB}{BC}=\frac{24}{8\sqrt{3}}=\sqrt{3}\,\,\,\,\Rightarrow \,\,\,\theta =60{}^\circ \] So, elevation angle of Sun \[=60{}^\circ \]
