Question

To solve this question you have to use TAN COS SIN i give brainiest

Answer 1

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 2

Answer:

• 4.3

Step-by-step explanation:

Here we will use cosine to find the value..

$\cos = \frac{adjacent}{hypotenuse}$

$\cos∠l = \frac{kl}{jl}$

$\cos21° = \frac{4}{x}$

$x = \frac{4}{ \cos21° }$

$x = 4.3$ When rounded off...
