Question

In the right triangle shown

Answer 1

Answer:

BC = 6

Step-by-step explanation:

Using the sine ratio in the right triangle and exact value

sin30° = $\frac{1}{2}$

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{x}{12}$ = $\frac{1}{2}$ ( cross- multiply )

2x = 12 ( divide both sides by 2 )

x = 6

That is BC = 6
