Answer:
16.97
Step-by-step 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
