Question

Help please!!! I don’t understand this question

Answer 1

C

Explanation:

Let us first write an equation. Using the SOHCAHTOA rule, we should know that the tangent of an angle equals it's
`(opposite)/(adjacent)`. The opposite of our given 20° angle is 9, and the adjacent side is x.

`tan(20`°
`)=(9)/(x)`

`0.364=(9)/(x) \\x=(9)/(0.364)\\x=24.7`
