Question

Please Help. If ∠P is given as well as the values of p, q, and r, then explain whether the Law of Sines or the Law of Cosines should be used to solve for ∠Q. Law of Cosines, two sides and the opposite angle are known Law of Cosines, all sides are known Law of Sines, two angles and an opposite side are known Law of Sines, two sides and an included angle are known

Answer 1

Answer:

Law of Sines, two angles and an opposite side are known

Step-by-step explanation:

got it on my test

Answer 2

Answer:

Both Law of Sines and Cosines can be used to determine the angle Q.

Step-by-step explanation:.

Since from Law of Sines with one angle and three sides we can find other angles using the ratio obtained with the given angle and side length opposite side if angle P is not given we couldn't use this.

Law of Cosines can be used to find any angle of triangle with all three side lengths given and angle P is also not required to find angle Q.
