Answer:

x=
8√(2) or 11.31

Explanation:

You know that the shape is a square that is divided making 2 triangles. They are examples of 45-45-90 degree triangles. So with this information, you know that both lengths of the triangles are equal, with a hypotenuse of 16.

Side C= 16

Side A= Side B

45-45-90 Formula

Side C=
a√(2)

16=
a√(2)


(16= a√(2))^(2)

256=
2a^(2)

128=
a^(2)


√(128)=a

a=
8√(2) or 11.31

Answer:

x = 8√2

Explanation:

use the pythagorean theorem with the 2 sides being the same

16^2 = x^2 + x^2

256 = 2x^2

Divide both sides by 2

128 = x^2

Take the square root of both sides

x = √128

x = √(64 * 2)

x = 8√2
