Helppp! find the missing triangle side length below using pythagorean theorem. leave answer in simplified radical form please!

The side a measures units and the side x measures units.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.

We use the triangle with sides 7 and 2 as we do not know the length of side x in the first triangle

In the given triangle, the hypotenuse is the side that is represented by a. The other sides on the triangle measure 7 and 2 units.

Step 2:

So according to the Pythagorean theorem,

Step 3:

Now for the first triangle, the same Pythagorean theorem can be used.

The length of the hypotenuse is and the sides of the triangle are 5 and x.

So

28 can be written as 7 times 4 and the root of 4 is 2 so .

The length of x is

answer: options
