Answer 2

Step-by-step explanation:

Given- AB=5cm

angle ABC= 30°

according to diagram,

tan C = side opposite to angle C/ side adjacent to angle C

tan 30° = AB/BC

1/√3 = 5/BC

BC = 5√3 cm

sin C = side opposite to angle C/ hypotenuse

sin 30° = AB/AC

1/2 = 5/AC

AC = 10 cm

hence, AC = 10 cm & BC = 5√3 cm.

hope it helps u, pls mark it brainliest answer.
