    Given:
    Height of the first pole = 20m,
    Height of the second pole = 14m,
    Angle of the wire with the horizontal = 30°.

    Find the vertical difference
    Vertical difference = 20 – 14 = 6m.

    Use the sine function
    sinθ = (Vertical difference) / (Length of the wire).
    sin30° = 6 / L.

    From trigonometric values, sin30° = 1/2:
    1/2 = 6 / L.

    Solve for L
    L = 6 × 2 = 12m.

  2. Given: - Observer is 200m above the lake. - Angle of elevation of cloud = 30°. - Angle of depression of reflection = 60°. Using tangent for both angles: 1. tan30° = (h - 200) / d ⇒ d = √3(h - 200). 2. tan60° = (h + 200) / d ⇒ √3 = (h + 200) / d. Substitute d = √3(h - 200) into the second equation: √Read more

    Given:
    – Observer is 200m above the lake.
    – Angle of elevation of cloud = 30°.
    – Angle of depression of reflection = 60°.

    Using tangent for both angles:
    1. tan30° = (h – 200) / d ⇒ d = √3(h – 200).
    2. tan60° = (h + 200) / d ⇒ √3 = (h + 200) / d.

    Substitute d = √3(h – 200) into the second equation:
    √3 = (h + 200) / (√3(h – 200)).

    Simplify:
    3(h – 200) = h + 200.

    Solve for h:
    2h = 800 ⇒ h = 400.
