The kite is flying 106ft high.
This is calculated by understanding that if the kite is flying at a 45° a 45° 45° 90° triangle is formed between the kite line as the hypotenuse and the height as the right hand side of the triangle. In this kind of triangle the base and height of the triangle are the same size and the length of the hypotenuse = (height)âš2. 150 divided by âš2 results in 106ft, rounded to the amount of decimals present in the original question.
