Answer:

33.18208

Step-by-step explanation:

This can be solved via Law of Sines, but I´m gonna use sines for the sake of efficiency. :P

So, you have your 3 values and unknown length x.

First set up your proportions: [tex]\frac{sin(65)}{x}=\frac{sin(35)}{21}[/tex]

Cross multiply. [tex]x=\frac{21sin(65)}{sin(35)}[/tex]

Simplify. [tex]x=33.18208[/tex]
