Answer:
3.92 feet
Step-by-step explanation:
The set up will be a right triangle
Given
Hypotenuse = 10feet (length of the ladder)
Opposite = 9.2 feet (Height of the slide)
Required
Length of the base l
USing the pythagoras theorem
adj^2 = hyp^2 - opp^2
l^2 = 10^2-9.2^2
l^2 = 100 - 84.64
l^2 = 15.36
l = 3.92 feet
Hence the base length is 3.92 feet
