Answer 1

Answer:

$c = 4$

Step-by-step explanation:

For this triangle we have to

$A=63\\C=49\°\\c=3\°$

Now we use the sine theorem to find the length of a:

$\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}$

Then:

$\frac{sin(A)}{a}=\frac{sin(C)}{c}\\\\a=\frac{sin(A)}{\frac{sin(C)}{c}}\\\\a=c*\frac{sin(A)}{sin(C)}\\\\a=(3)\frac{sin(63)}{sin(49)}\\\\c=4$
