12 km
Figure not drawn to scale
I
C=
Kilometers

Answer 1

c = 20 Km

Explanation:

using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other two sides , that is

c² = 12² + 16² = 144 + 256 = 400 ( take square root of both sides )

c =
`√(400)` = 20
