Answer:

3rd Option is correct.

Step-by-step explanation:

Given:

Angle of elevation from L to K = 39°

J is the vertex of the Right angled triangle.

To find: JL

Figure is attached.

In ΔJKL,

Using Trigonometric ratio,

\(cos\:39=\frac{JL}{KL}\)

\(0.77=\frac{JL}{12}\)

JL = 0.77 × 12

JL = 9.324

JL = 9.3

Therefore, 3rd Option is correct.
