Question

in a ∆ABC right angled at B. angle A is 30° and AC is 6cm, then the length of BC is​

Answer 1

Step-by-step explanation:

Look at the attachment:

SinA=BC/AC.

sin30°=BC/AC.

1/2=BC/6.

6/2=3cm=BC.

Answer 2

Answer:6/3 therefore bc =3cm

Step-by-step explanation:

SinA=BC/AC.

sin30°=BC/AC.

1/2=BC/6.

6/2=3cm=BC.
