Answer: The approximate distance between the swing and the slide is 56.21 feet.
Explanation:
Since we have given that
Distance between bench and swing = 100 feet
Distance between bench and slide = 60 feet
Angle between them is given by

So, we will use "Cosine law" to get the distance between the swing and the slide i.e.,

Hence, the approximate distance between the swing and the slide is 56.21 feet.
