The value of n to the nearest whole number is 22
<h3>Trigonometry</h3>
From the question, we are to determine the value of n to the nearest whole number
In the diagram,
The given triangle is a right triangle.
Thus,
Using the <em>Pythagorean theorem</em>, we have that
n² = h² + k²
∴ n² = 9² + 20²
n² = 81 + 400
n² = 481
n = √481
n = 21.93
n ≈ 22
Hence, the value of n to the nearest whole number is 22
