Question

If a pole of height 6 m casts a shadow $2\sqrt{3}$ long on the ground, then the suns elevation is.

• A. ${30}^{\circ }$
• B. ${60}^{\circ }$
• C. ${45}^{\circ }$
• D. ${90}^{\circ }$

Answer 1

Answer: (B)

${60}^{\circ }$

as we can observe that,
The Angle of Elevation of Sun at point $P$ is equal to the Angle of Elevation of the Building at point $P.$
so, $\tan A=\frac{6}{b}=\frac{6}{2\sqrt{3}}=\sqrt{3}\Rightarrow A={60}^o$
Therefore, Answer is ${60}^o$
