Answer:
28°
Step-by-step explanation:
[tex] \frac{ \sin(120) }{13} = \frac{ \sin(c) }{7}[/tex]
[tex]0.866(7) = \sin(c) 13[/tex]
[tex]6.062 = 13 \sin(c) [/tex]
Divide both by 13
[tex] \sin(c) = 0.4663[/tex]
Move sin to the right side and that would become sin-1
[tex]c = { \sin }^{ - 1} (0.4663)[/tex]
[tex]c = 27.79438831[/tex]
Or if your round it off, c=28
