A kite flies on a taut string of length 50m inclined at tan angle 54o to the horizontal ground. The height of the kite above the ground is
50 tan 30o
50 sin 54o
50 tan 54o
50 sin 36o
Explanation
From the diagram above,
Sin 54º = \(\frac{\text{OPP}}{\text{HYP}}\)
Sin 54º = \(\frac{\text{x}}{50}\)
x = 50 Sin 54º
