Answer:
x = √17
Explanation:
Your question have a right triangle.
So, we could use the Pythagorean Theorem.
Pythagorean Theorem is a² + b² = c².
So, 8² + n² = 9².
8² is 64, and 9² is 81.
So, 'n' is 81 - 64.
Let's see... 81 - 64 is 17.
So, It is √17.
Because when you use the Pythagorean Theorem, it is 8² + (√17)² = 9².
Otherwise, 64 + (√17)² = 81.
And, √17 is 4.12 when rounding to a hundredth.
Hope it helps!
