Answer:

A=2.2

Step-by-step explanation:

PYTHAGOREAN THEOREM:

a^2+b^2=c^2

STEP 1:

Lets put in the given number into the Theorem.

x^2+ 2^2= 3^2

I put x in the "a" place because there is no Number that goes into there, so we put in a variable.

STEP 2:

We find the numbers, which are

x^2+4=9

STEP 3:

We then subtract by 4 from both sides, (We do this because x is not the Hypotenuse)

After subtracting from both sides we have

x^2=5

STEP 4:

Once we have that, we have to find the square root of 5 which is  2.23606798

STEP 5:

Since you say to round to the nearest tenth, we get 2.2

TIP: If the answer didn't have to be rounded to the nearest tenth the answer would've been: [tex]x=\sqrt{5}[/tex]  Which is the same as 2.23606798.
