Answer 1

BC= 11.9 cm or you can say almost 12 cm

Answer 2

Answer:

BC ≈ 11.9 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin58° = $\frac{opposite}{hypotenuse}$ = $\frac{BC}{AC}$ = $\frac{BC}{14}$ ( multiply both sides by 14 )

14 × sin58° = BC , then

BC ≈ 11.9 cm ( to 1 dec. place )
