Answer:
The answer to your question is L = 35.94 u
Step-by-step explanation:
Process
1.- Find the length of "h"
[tex]\frac{h}{sin 10} = \frac{200}{sin 90}[/tex]
h = [tex]\frac{200sin10}{sin90}[/tex]
h = 34.72 u
2.- Find the length of "L"
[tex]\frac{34.72}{sin 75} = \frac{L}{sin 90}[/tex]
[tex]L = \frac{34.72sin 90}{sin 75}[/tex]
L = 35.94 u
