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,
[tex]cos\:39=\frac{JL}{KL}[/tex]
[tex]0.77=\frac{JL}{12}[/tex]
JL = 0.77 × 12
JL = 9.324
JL = 9.3
Therefore, 3rd Option is correct.
