## kenneyfamily Group Title Given A = 67o, B = 13o, and b = 20.3, which of the following can be used to solve the triangle? a. Law of Sines b. Law of Cosines c. Hero's Formula d. Cannot be solved. one year ago one year ago

1. kenneyfamily Group Title

those are degrees

2. AERONIK Group Title

cosine formula is a good option

3. freewilly922 Group Title

Ah. Law of sines: $\frac{\sin(a)}{A}=\frac{\sin(b)}{b}$ Law of cosines is $c^2 = a^2+b^2 - 2ab\cos(C)$ So what are you given that can be used here?

4. Praja_01 Group Title

cannot be solved

5. freewilly922 Group Title

Sorry the law of sines should have been: $\frac{\sin(A)}{a}=\frac{\sin(B)}{b}$

6. kenneyfamily Group Title

the angles

7. kenneyfamily Group Title

oh and side b

8. freewilly922 Group Title

Yes it can. You have 1 side and three angles

9. kenneyfamily Group Title

so law of sines?

And i flipped all my capitol letters with the convention. Yes, Multiple uses of Law of sines would solve the triangle. You would have to do a 180-a-b to get angle c though...
