Answer:

  26.1 ft

Step-by-step explanation:

The height of the kite above your position is the opposite side of a right triangle whose hypotenuse is 50 ft. The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

Filling in the known values, we have ...

  sin(25°) = height/(50 ft)

  height = (50 ft)sin(25°) ≈ 21.1 ft

Added to the height at which you are holding the string, this becomes the total height of the kite.

  h = 5 ft + 21.1 ft = 26.1 ft . . . . total height of the kite
