Answer:
x ≈ 7.2
Step-by-step 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 = 14²
x² + 144 = 196 ( subtract 144 from both sides )
x² = 52 ( take square root of both sides )
x = ≈ 7.2 ( to the nearest tenth )
