Answer:

0.0707 cm

Step-by-step explanation:

We can solve this using pythgaoras theorem:

a² + a² = c² (We can use the same letter, a, because the lengths are the same length; a² + a² = 2a²)

2a² = 0.1² (simplify the right side; 0.1 × 0.1 = 0.01)

2a² = 0.01 (0.01 ÷ 2 = 0.005)

a² = 0.005 (square root both sides)

a = 0.070710... ≈ 0.0707 cm

Hope this helps!

Answer:

  • The value of x is 0.071 cm.

Step-by-step explanation:

<u>Using Pythagoras theorem, let's solve for x.</u>

  • 0.1² = x² + x²
  • => 0.01 = 2x²
  • => 0.01/2 = 2x²/2
  • => 0.005 = x²
  • => √0.005 = √x²
  • => √0.005 = x
  • => x = 0.071 (Rounded to nearest thousandth)

Hence, the value of x is 0.071 cm.
