Find the angle of elevation of the sun when the shadow of a pole of 18 m height is 6 √ 3 m long? A. 90° B. 80° C. 70° D. 60° Answer Workspace Report Discuss Answer with explanation Answer: Option D Explanation Let RQ be the pole and PQ be the shadow Given that RQ = 18 m and PQ =6√3 m Let the angle of elevation, RPQ = θ From the right PQR, tanθ=RQ/PQ =18/(6√3) =3/√3 =√3 ⇒θ=tan−1(√3)=60° Workspace
RPQ = θ
