Triangle Side Length using Law of Sines

Very Hard Geometry Shapes And Properties

Consider a triangle ABC where angle A measures 60 degrees, angle B measures 80 degrees, and side a opposite angle A is 10 cm long. Determine the length of side b opposite angle B using the Law of Sines.

The Law of Sines states that: $$ \frac{a}{\sin A} = \frac{b}{\sin B} $$

Calculate the value of side b.

$$ 8.5 \text{ cm} $$

$$ 9.5 \text{ cm} $$

$$ 10.5 \text{ cm} $$

$$ 11.5 \text{ cm} $$
