Question

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

Answer 1

x = 10.2

Explanation:

To find x, use Cosine

Cosine =
`(adjacent)/(hypothenuse)`

⇒ Cosine 22 =
`(x)/(11)`

Cosine of 22 is 0.93

⇒ 0.93 =
`(x)/(11)`

Multiply 11 on both sides:

⇒ 0.93 x 11 =
`(x)/(11)` x 11

⇒ 10.23

Round to the nearest tenth:

10.23 ⇒ 10.2

x = 10.2
