Answer :
Final answer:
Using Sine Law or Cosine Law with known angle measurements in a triangle is not sensible; instead, the Law of Sines or Law of Cosines should be used to find side lengths accurately.
Explanation:
The reason it is not sensible to use either Sine Law or Cosine Law to find the lengths of the sides of a triangle when you know the angle measurements is because these laws are mainly used when information about side lengths and angles in a triangle are incomplete.
When you have the angle measurements and want to find side lengths, it is more appropriate to use the Law of Sines or Law of Cosines. The Law of Sines can be used to find sides and angles of non-right triangles, while the Law of Cosines is suitable for finding side lengths in any triangle when all angles are known.
Trying to apply the Sine Law or Cosine Law when all angle measurements are known would add unnecessary complexity since these laws are more beneficial when dealing with incomplete information about the triangle's sides and angles.
