Answer» Step-by-step explanation: Let CE is a pole of height H meter. AD is a hill of height 200 m. Let distance between bottom of hill to pole = x m. According to question ∠XAC= 30° = ∠ACB and ∠XAE = 60° = ∠AED From right angled ∆ADE TAN 60° = AD/DE ⇒ √81 = 200/x ⇒ x = 200/√3 m From right angled ∆ABC, HENCE, height of pole = 133.33 m. |
