What is the value of x? 5 sqrt 2 10 sqrt 2 5 10

Hey there! :D

So, basically, you could say that "x" is equal to both of the legs. 

We also know that in 45-45-90 triangles, x*√2= the hypotenuse

Given this information, if we were to divide 10 by the √2, we would get:

10/√2= 7.071 

5√2= 7.071

5√2 is the answer. 

I hope this helps!

Volume = the base times the height. i’m not going your work for you, but this is all you need to know.

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"
