What does AC=?<br> Round your answer to the nearest hundredth. <br><br> Please help

faltersainse [42]

Answer: About 3.06

Step-by-step explanation:

We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

cos(θ) = $\frac{adjacent}{hypotenuse }$

cos(40) = $\frac{x}{4}$

0.766 ≈ $\frac{x}{4}$

3.06 ≈ x

x ≈ 3.06
