## The Attempt at a Solution

c

^{2}= a

^{2}+ b

^{2}- 2abcosC

c = (a

^{2}+ b

^{2}- 2abcosC)

^{1/2}

c = [ (32.0 N)

^{2}+ (38.0 N)

^{2}- 2 (32.0 N) x (38.0 N) cos 55° ]

^{1/2}

c = 32.8 N

sinA/ 38.0 N = sin55° / 32.8 N

A= 72°

F

_{net}= 32.8 N [ N 72° E]

Can someone please check my answer and tell me if it is correct? Thanks.
