It seems you're dealing with a right-angled triangle, where:
- The hypotenuse (Hyp) is 11.8 cm.
- The adjacent side (Adj) is 8.9 cm.

You can use the Pythagorean theorem to find the missing side (let's call it Opp, the opposite side):

\[ \text{Hyp}^2 = \text{Adj}^2 + \text{Opp}^2 \]

Substitute the given values:

\[ 11.8^2 = 8.9^2 + \text{Opp}^2 \]

Now, solve for Opp:

\[ 139.24 = 79.21 + \text{Opp}^2 \]

\[ \text{Opp}^2 = 60.03 \]

\[ \text{Opp} = \sqrt{60.03} \]

\[ \text{Opp} \approx 7.76 \]

Therefore, the missing side (Opp) is approximately 7.76 cm.
