Answer:
7
Step-by-step explanation:
The diagonal is the hypotenuse of the right triangle with legs 7
Use Pythagoras' identity to solve for the diagonal d
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
d² = (7)² + (7)²
= 147 + 147
= 294 ( take the square root of both sides )
d = 
= 7 ≈ 45.37 ( to 2 dec. places )

Answer:
n = 144
Step-by-step explanation:
6 / n = 5/120
