To find the distance between Jack and Liz, we can use the Pythagorean theorem. The vertical height of the rock face (16 meters) and the horizontal distance from Liz to the bottom of the cliff (12 meters) form a right triangle, with the distance between Jack and Liz being the hypotenuse.
Let:
- \( a = 16 \) meters (the height of the rock face)
- \( b = 12 \) meters (the horizontal distance)
According to the Pythagorean theorem: \[ c^2 = a^2 + b^2 \]
Substituting the values: \[ c^2 = (16)^2 + (12)^2 \] \[ c^2 = 256 + 144 \] \[ c^2 = 400 \] \[ c = \sqrt{400} = 20 \]
So, the distance between Jack and Liz is 20 meters.
