## aussy123 Group Title Given: a = 8, b = 6, Angle C = 60 Angle A = 14° 46° 74° 106° one year ago one year ago

1. phi

we could use the law of cosines to find side c, and then the law of sines to find angle A

2. begzat

i The only angle you are given is C, so use c^2 = a^2 + b^2 - 2abcosC...now substitute

3. aussy123

Would you use the formula a^2=b^2+c^2-2bcCosA

4. begzat

yes

5. aussy123

okay thanks ill try

6. begzat

okay

7. phi

This is a 2 step problem. find side c using $c^2 = a^2 + b^2 - 2\ a\ b \cos(C)$ after you find c, you can use the Law of Sines $\frac{\sin A}{a}= \frac{\sin C}{c}$

okay thanks
