Answer 2

Answer:

9.4 = x

Step-by-step explanation:

You are given the hypotenuse and the adjacent side, leading you to use cosine.

Set it up:

$cos48 = \frac{x}{14}$

Multiply everything by 14, to remove it from the denominator:

$14(cos48 = \frac{x}{14})$

$14cos48=x$

Multiply accordingly:

9.36 = x

Round to nearest tenth:

9.4 = x
