Answer:
The law of Sines is used to determine a missing side or angle measurement
Step-by-step explanation:
When saying Sine Law, I am pretty sure you mean the Law of Sines.
This is the equation
a/sine a = b/sine b
To use the Law of Sines you need 2 angle measurements and 1 side length, or 2 side lengths and 1 angle measurements. Law of Sines is used to find the missing angle or side. Not to find the third side.
To find the length of the third side you would use pythagorean theorem.
