Answer:
[tex]AB = 21.3[/tex]
Step-by-step explanation:
Given
[tex]\sin(25) = \frac{9}{c}[/tex]
See attachment
Required
Find AB
We have:
[tex]\sin(25) = \frac{9}{c}[/tex]
Make c the subject
[tex]c = \frac{9}{\sin(25)}[/tex]
[tex]c = 21.3[/tex]
From the attached triangle;
[tex]AB = c = 21.3[/tex]
Hence:
[tex]AB = 21.3[/tex]
