Answer 1

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: $\frac{sin(65)}{x}=\frac{sin(35)}{21}$

Cross multiply. $x=\frac{21sin(65)}{sin(35)}$

Simplify. $x=33.18208$
