The angle of elevation from l to k measures 39°. if kl = 12, find jl. round your answer to the nearest tenth.

7.6

9.7

9.3

8.1

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,

JL = 0.77 × 12

JL = 9.324

JL = 9.3

Therefore, 3rd Option is correct.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
