The diagram representing this scenario is shown below
h represents how high the kite is in the air.
The triangle formed is a right triangle. Taking 36 degrees as the reference angle,
hypotenuse = 40
opposite side = h
We would find h by applying the sine trigonometric ratio which is expressed as
Sinθ = opposite side/hypotenuse
By substituting the values,
Sin 36 = h/40
By crossmultiplying, we have
h = 40Sin36
h = 23.51
The height of the kite in the air is 23.51 feet
