Answer:

[tex]A. 10\sqrt{2}[/tex]

Step-by-step explanation:

The triangle is a 45-45-90 triangle, which has the property that the side across from the 90°, in this case, x, is equal to one of the other sides multiplied by [tex]\sqrt{2}[/tex].

So:

10 x [tex]\sqrt{2}[/tex] = [tex]10\sqrt{2}[/tex]

Answer:

A.

Step-by-step explanation:

x = 10[tex]\sqrt{2}[/tex] cause it is 10 times [tex]\sqrt{2}[/tex]. This is cause its a 45-45 triangle
