Answer:

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

C

I hope this helps! Let me know if you have any questions :)
