<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.

Is the function represented by the table linear
Bess [88]

Answer:

No, because it does not have a constant rate of change.

Step-by-step explanation:

On the <em>x</em><em> </em>side of the table, there is a constant rate of change (+1). However, on the y side, it is not. The first change is +7, the next +5, and the last +6. The rate of change has to be constant on both sides for the table to be considered linear.
