  1. Answer:

    • the height of kite is 44.7m

    To Find:

    • the height of the kite correct to one decimal place.

    Given:

    • Angle of elevation of the kite = 26° 32′

    • lenght of string = 100m

    Consider:

    • AB as the height of the kite A and AC as the string,

    • → AC = 100
    • → Take AB = x

    In right triangle ABC

    • => Sin∅ = [tex]\frac{AB}{AC}[/tex]

    [tex] \:\:\:Substituting\:the\:values,[/tex]

    • ⇒sin26° 32′ = [tex]\frac{x}{100}[/tex]
    • ⇒0.4467 = [tex]\frac{x}{100}[/tex]
    • ⇒x = 100 × 0.4467
    • ⇒x = 44.67 ≈ 44.7m

    Hence, the height of the kite is 44.7 m.
