Question

Find angle B. What is angle B.

Answer 1

Answer:

B=45 Degrees

Step-by-step explanation:

You can use law of sines to answer. Law of Sines states that $\frac{sin(a)}{A} =\frac{sin(b)}{B}$. That means that $\frac{sin(60)}{4\sqrt{6} }=\frac{sin(b)}{8}$. Multiplying 8 to both sides gives us $\frac{8sin(60)}{4\sqrt{6} }=sin(b)$. By using inverse of sin, we get $b = sin^{-1} (\frac{8sin(60)}{4\sqrt{6} } )$. Plugging that into a calculator gives us b=45 degrees.
