In the right triangle shown

Mathematics
1 answer:
Semmy [17]3 years ago
3 0

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
