Aright triangle has legs of 12 ft and 16 ft. find the longest side of the triangle. i don't get this at all : (

longest side = 20 ft

Step-by-step explanation:

In a right triangle the longest side is the side opposite the right angle.

This side is called the hypotenuse and we can calculate it using Pythagoras' identity.

let h be the hypotenuse, then

h² = 12² + 16² = 144 + 256 = 400

h² = 400 ( take the square root of both sides )

h = = 20 ← longest side
