Question

Find angle x, giving your answer to 1 decimal place.
38°
х
11 cm
8 cm

Answer 1

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)

$\frac{ \sin(38) }{8} + \frac{ \sin(x) }{11}$

$11 \times \frac{ \sin(38) }{8}$

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

=0.84653452.....

$\sin^{ - 1} (0.84653452)$

=57.83672257
