Answer:

  • 4.3

Step-by-step explanation:

Use cosine:

  • cos = adjacent / hypotenuse
  • cos ∠L = KL/JL
  • cos 21° = 4/x
  • x = 4 / cos 21°
  • x = 4.3 (rounded)

Answer:

  • 4.3

Step-by-step explanation:

Here we will use cosine to find the value..

[tex] \cos = \frac{adjacent}{hypotenuse} [/tex]

[tex] \cos∠l = \frac{kl}{jl} [/tex]

[tex] \cos21° = \frac{4}{x} [/tex]

[tex]x = \frac{4}{ \cos21° } [/tex]

[tex]x = 4.3[/tex] When rounded off...
