Question

Find the value of x. Round to the nearest tenth.

Answer 1

Answer:

x = 10.2

Step-by-step explanation:

To find x, use Cosine

Cosine = $\frac{adjacent}{hypothenuse}$

⇒ Cosine 22 = $\frac{x}{11}$

Cosine of 22 is 0.93

⇒ 0.93 =  $\frac{x}{11}$

Multiply 11 on both sides:

⇒ 0.93 x 11 = $\frac{x}{11}$ x 11

⇒ 10.23

Round to the nearest tenth:

10.23 ⇒ 10.2

x = 10.2
