To find the length of \( JW \), which is the hypotenuse of the right triangle with legs \( JE \) and \( EW \), we can apply the Pythagorean theorem. The Pythagorean theorem states that in a right triangle:

\[
c^2 = a^2 + b^2
\]

where:
- \( c \) is the length of the hypotenuse,
- \( a \) and \( b \) are the lengths of the legs.

In our case:
- \( a = JE = 4.8 \)
- \( b = EW = 28.6 \)
- We want to find \( JW \) (which is \( c \)).

Now, substituting the values into the formula:

\[
JW^2 = JE^2 + EW^2
\]

Calculating \( JE^2 \):

\[
JE^2 = (4.8)^2 = 23.04
\]

Calculating \( EW^2 \):

\[
EW^2 = (28.6)^2 = 816.96
\]

Now we can substitute these values back into the Pythagorean theorem:

\[
JW^2 = 23.04 + 816.96 = 840
\]

To find \( JW \), we take the square root of both sides:

\[
JW = \sqrt{840}
\]

Now we will calculate \( \sqrt{840} \):

\[
JW \approx 29.0
\]

Finally, rounding to the nearest tenth, we find that the length of \( JW \) is:

\[
\boxed{29.0}
\]

I apologize for any confusion; however, it appears that you are mixing up the values. Let me clarify and recalculate the solution step-by-step.

Given:
- \( JE = 4.8 \)
- \( EW = 28.6 \)

We need to find the length of the hypotenuse \( JW \) in the right triangle, where \( JE \) and \( EW \) represent the two legs.

Using the Pythagorean theorem:
\[
c^2 = a^2 + b^2
\]
where:
- \( c = JW \)
- \( a = JE = 4.8 \)
- \( b = EW = 28.6 \)

Substituting in the values:
\[
JW^2 = JE^2 + EW^2
\]

Calculating each part:

1. Calculate \( JE^2 \):
\[
JE^2 = (4.8)^2 = 23.04
\]

2. Calculate \( EW^2 \):
\[
EW^2 = (28.6)^2 = 816.96
\]

Now substitute back into the theorem:
\[
JW^2 = 23.04 + 816.96
\]

Calculating this sum:
\[
JW^2 = 840
\]

Now take the square root to find \( JW \):
\[
JW = \sqrt{840}
\]

Calculating the square root:
\[
JW \approx 29.0
\]

So, rounding to the nearest tenth, the length of \( JW \) is:
\[
\boxed{29.0}
\]
