Determine the side length.
White raven [17]

Answer:

3

Step-by-step explanation:

The given shape is a right angled triangle.

Here,

Hypotenuse = 2√3

Another side = √3

Let the missing side length be " x ".

By Hypotenuse theorem,

x² + ( √3 )² = ( 2√3 )²

x² + 3 = 12

x² = 12 - 3

x² = 9

x² = 3²

x = 3

Therefore, the side length is 3.
