Calculate Side Length Using Law of Sines

Easy Additional Math Topics Trigonometry

In triangle ABC, angle A measures 30 degrees and side a measures 10 units, where side a is opposite angle A. To find the length of side b, which is opposite angle B (where angle B measures 60 degrees), use the Law of Sines.

Recall that the Law of Sines states:

$$ \frac{a}{\sin A} = \frac{b}{\sin B} $$

Using this information, calculate the length of side b to one decimal place.
