Answer:

The answer is option D.

<h2>LJ = 3.5</h2>

Step-by-step explanation:

<u>To find LJ we use the sine rule</u>

From the picture

LK / sin J = LJ / sin K

LK = 9

J = 89°

K = 23°

So now LJ is

9 / sin 89° = LJ / sin 23°

<u>Make LJ the subject</u>

That's

LJ = 9 sin 23° / sin 89°

LJ = 3.51

The final answer is

<h3>LJ = 3.5</h3>

Hope this helps you.
