Answer:

16.97

Explanation:

To solve for a missing side in a right angles triangle, we solve using Pythagoras Theorem.

Pythagoras Theorem =

a² + b² = c²

Where c = Hypotenuse = Longest side

From the question above,

a=6 and c=18,

Hence,

6² + b² = 18²

b² = 18² - 6²

b² = 18² - 6²

b² = 324 - 36

b²= 288

Square root both sides

b = √288

b = 16.970562748

Approximately b ≈ 16.97
