Answer:
x ≈ 5.4 feet
Explanation:
using Pythagoras' identity in the right triangle
the square on the hypotenuse x is equal to the sum of the squares on the other 2 sides.
horizontal leg = 5 units = 5 feet
vertical leg = 2 units = 2 feet
Then
x² = 5² + 2² = 25 + 4 = 29 ( take square root of both sides )
x =
≈ 5.4 feet ( to the nearest tenth of a foot )
