Answer 1

The answer is option D.

LJ = 3.5

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.
