Question

I would really appreciate it if someone could answer this I will give a brainlist:)

Answer 1

5.7

Pythagorean Theorem is a² + b² =  c²

Answer 2

Answer:

x = 5.7

Step-by-step explanation:

Formula:

a² + b² = c²

4² + b² = 7²

16 + b² = 49

b² = 49 - 16

b² = 33

$\sqrt{b^2} =\sqrt{33}$

b = 5.7
