Question

I need some help with this I don't quiet get this.​

Answer 1

13, or 13.1

Explanation:

For this problem, we have a Right Triangle. We should use the Tangent of 54°.

`Tangent \ = \ (Opposite \ Side)/(Adjacent \ Side)`

(Use a Calculator to find x)

Tan(54°) =
`(18)/(x)`

Divide 18 by Tan(54°):

`(18)/(tan(54))` ≈
`13 \ or \ 13.1 \ (tenths \ place)`

x ≈ 13, 13.1
