Answer is :

Step-by-step explanation :

Using trigonometric ratio,

$(P)/(H)= \sin \theta$

Here P refers to perpendicularand H refers to the hypotenuse.

Since perpendicular is BC And Hypotenuse is AC

Plugging in the values

$(BC)/(AC) = \sin 30\degree$

$\bigg( \because\sin30 \degree = (1)/(2) \bigg)$

(BC)/(6) = (1)/(2)

further we can solve by cross multiplication,

2 * BC = 6

BC = (6)/(2)

BC = 3 cm

The value of BC is 3 cm
