Answer:

a = 3.5

Step-by-step explanation:

[tex]\frac{a}{sin(A)} = \frac{c}{sin(C)} \\\\a = \frac{csin(A)}{sin( C )} \\\\a = \frac{3 sin(63^{o} )}{sin(49^{o} )} \\\\a = 3.5[/tex]

Answer:

3.54

Step-by-step explanation:

Use sin law:

c/sin(C) = a/sin(A)

3/sin(49) = a/sin(63)

a = 3/sin(49) × sin(63)

a = 3.54 (3 sf)
