Answer 2

Answer:

x = 3

Step-by-step explanation:

Use Pythagorean Theorem:

4² + x² = (x+2)²

Expand and simplify:

16 + x² = x² + 4x +4

The x² cancel out leaving 16 = 4x +4

Now just solve for x:

Subtracting 4 from both sides gives 12 = 4x

x = 3

You can double check this by substituting 3 into x:

4²+3² = (3+2)²

16 + 9 = 25
