Answer:
The answer is option D.
LJ = 3.5
Step-by-step explanation:
To find LJ we use the sine rule
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°
Make LJ the subject
That's
LJ = 9 sin 23° / sin 89°
LJ = 3.51
The final answer is
LJ = 3.5
Hope this helps you.
