  • Answer:

    BC ≈ 11.9 cm

    Step-by-step explanation:

    Using the sine ratio in the right triangle

    sin58° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{14}[/tex]

    Multiply both sides by 14

    14 × sin58° = BC, thus

    BC ≈ 11.9 cm ( to 1 dec. place )
