To find the length of the ramp using the Pythagorean theorem, we can model the ramp, the height of the ramp, and the horizontal distance as a right triangle, where:
- \(a\) is the height of the ramp (6 feet),
- \(b\) is the horizontal distance (8 feet),
- \(c\) is the length of the ramp (the hypotenuse).
According to the Pythagorean theorem: \[ c^2 = a^2 + b^2 \]
Substituting the values we have: \[ c^2 = 6^2 + 8^2 \] \[ c^2 = 36 + 64 \] \[ c^2 = 100 \]
Now, taking the square root of both sides to find \(c\): \[ c = \sqrt{100} = 10 \]
Thus, the length of the ramp is 10 feet.
