Answer:

x = 55.8

Step-by-step explanation:

sinA/a + sinB/b

label any of them A (the angle) and opposite it will be a (the side)

[tex] \frac{ \sin(38) }{8} + \frac{ \sin(x) }{11} [/tex]

[tex]11 \times \frac{ \sin(38) }{8} [/tex]

(you can put ×11 the opposite area as well, it makes the same answer)

=0.84653452.....

[tex] \sin^{ - 1} (0.84653452)[/tex]

=57.83672257
