Question

The Law of Sines: Mastery Test ? In triangle ABC, how long is side a if A = 24°, C = 55°, and c = 3? O 1.49 O 1.31 O 6.04 O 0.1 ​

Answer 1

Explanation:

Using the Law of Sines, our proportion would be

`(sin24)/(a)= (sin55)/(3)` and cross multiply to get

3sin24 = asin55 and solve for a:

`a=(3sin24)/(sin55)` so

a = 1.49, the first choice.
