Question

In triangle ABC, m∠A=35°, m∠B=60°, and the length of side AB is 6 cm. Find the length of side BC using the law of sines.

Answer 1

3.45cm is the correct answer!

Answer 2

3.97cm

Explanation:

Law of Sines formula =

a/ sin A = b/ sin B = c/sin c

We are told that

In a triangle

Side AB = b

Side BC = a

Hence

a/ sin A = b/ sin B =

a/ sin 35 = 6/ sin60

a = b(sin A/ sin B)

a = 6 (sin 35/sin 60)

a = 3.97385cm

Approximately = 3.97 cm
