Question

Find x
16 ft
х
12 ft

Answer 1

x = 20

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )

x =
`√(400)` = 20
