What is the angle of elevation of the sun when the shadow of a pole of height x m is \[\frac{x}{\sqrt{3}}m\]?
A)\[~30{}^\circ \]
B)\[45{}^\circ \]
C)\[60{}^\circ \]
D)
Correct Answer:
C
Solution :
Here, 9 is the angle of elevation \[\tan \theta =\frac{Perpendicular}{Base}=\frac{x}{\frac{x}{\sqrt{3}}}\] = \[\frac{\sqrt{3}x}{x}=3\,\,Here,\,\,\tan \theta =\sqrt{3}\] So, \[\theta ={{60}^{{}^\circ }}\]
