7.6

9.7

9.3

8.1

Answer 1

Answer is C=9.3

Pls find attached file

Answer 2

3rd Option is correct.

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=(JL)/(KL)`

`0.77=(JL)/(12)`

JL = 0.77 × 12

JL = 9.324

JL = 9.3

Therefore, 3rd Option is correct.
