Answer 1

$\large\green{\textsf{✩ Verified Answer ✓ }}$

a^2 + b^2 = c^2

b^2 = c^2 - a^2

b = sqrt(c^2 - a^2)

b = sqrt(3^2 - 1^2)

b = sqrt(9 - 1)

b = sqrt(8)

b = 2sqrt(2)

Answer 2

Step-by-step explanation:

a² + b² = c²

b² = c² - a²

b = sqrt(c² - a²)

b = sqrt(3² - 1²)

b = sqrt(9 - 1)

b = sqrt(8)

b = 2sqrt(2)
