The height of the superhero's hand above the ground is 66.17 feets.
Using pythagoras :
- a² = b² + c²
- where a = hypotenus
Here, the hypotenus = 61 ft
height, x² = 61² - 10²
height, x² = 3621
x = √3621
x = 60.17 feets
The height above the ground is :
Hence, the height of the superhero's hand above the ground is 66.17 feets.
