Answer:

47 m

Step-by-step explanation:

In the attached diagram, we find angle AKB to be ...

180° -55° -35° = 90°

Then the length of AK is ...

AK = AB·cos(35°)

and the height of the kite is ...

height = AK·sin(35°) = AB·sin(35°)cos(35°) = (AB/2)sin(2·35°)

height = 50·sin(70°) = 46.98

The height of the kite is about 47 meters.
