− 6
+ 8
Step-by-step explanation:
Use the law of sines.
![a/Sin(A) = b/Sin(B) = c/Sin(C)](https://tex.z-dn.net/?f=a%2FSin%28A%29%20%3D%20b%2FSin%28B%29%20%3D%20c%2FSin%28C%29)
SO:
![6.5/Sin(95') = 5/Sin(A)](https://tex.z-dn.net/?f=6.5%2FSin%2895%27%29%20%3D%205%2FSin%28A%29)
Next, you solve for A, Which gets you to the following solution for A
Sin(A) = (5 * Sin(95'))/6.5
This will give you the answer to A.
You then use A + 95 + B = 180 to find B.
The answer, therefore, is:
35'
