The image you uploaded shows a right triangle with the following information:

• The length of one side is labeled as 12 units.
• The length of the hypotenuse is labeled as 16 units.
• There is a right angle at vertex Σ (denoted by the small square).
• The third side is labeled as X.

This appears to be a Pythagorean theorem problem, where you can use the relationship $a^2 + b^2 = c^2$ to find the missing side $X$.

To solve for $X$, we apply the Pythagorean theorem:

$12^2 + X^2 = 16^2$

Let's calculate it step by step. Given values a = 12 # One side of the triangle c = 16 # Hypotenuse

Applying the Pythagorean theorem to find the missing side (X)

X = (c2 - a2)**0.5 # Solving for X

XThe missing side $X$ is approximately 10.58 units.
