Question

In the figure below, /BC/= 2cm, /AB/= 3cm and ZACD= 1500, what is the value of sin A? A D 150° с A√3 B √√3 2 2cm 2/3 3cm B DE 2 3​

Answer 1

E 1/3

Explanation:

m<ACB = 30° because of supplementary angles.

Use the Law of Sines

sin C/AB = sin A/BC

sin 30°/3 = sin A/2

sin A = (2 × sin 30°)/3

sin A = (2 × 0.5)/3

sin A = 1/3

Answer: E 1/3
