ANSWER
[tex]37.53units[/tex]
EXPLANATION
From the given right angle triangle the known angle is 47°
The side length which is x units is opposite to the known angle.
We also know a side length 35 units which is adjacent to the given angle.
We use the tangent ratio to obtain,
[tex] \tan(47 \degree) = \frac{opposite}{adjacent} [/tex]
[tex]\tan(47 \degree) = \frac{x}{35} [/tex]
[tex]x = 35\tan(47 \degree) = 37.53 \: units[/tex]
