Answer:

[tex]c=13.1\ units[/tex]

Step-by-step explanation:

step 1

Find the measure of angle C

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

so

A+B+C=180°

we have

A=57°

B=37°

substitute

57°+37°+C=180°

94°+C=180°

C=180°-94°=86°

step 2

Find the measure of side c

Applying the law of sines

[tex]\frac{a}{sin(A)}=\frac{c}{sin(C)}[/tex]

substitute

[tex]\frac{11}{sin(57\°)}=\frac{c}{sin(86\°)}[/tex]

[tex]c=\frac{11}{sin(57\°)}sin(86\°)[/tex]

[tex]c=13.1\ units[/tex]
