Answer:
Step-by-step explanation:
In trigonometry, to find the measure of angle in a triangle, you can use the Law of Sines or the Law of Cosines, depending on the information given:
1. Using the Law of Sines:
If you know at least one side and its opposite angle or two sides and an angle that is not between them, you can use the Law of Sines:
where , , and are the side lengths, and , , and are the opposite angles.
2. Using the Law of Cosines:
If you know all three sides of the triangle or two sides and the included angle, you can use the Law of Cosines:
where , , and are the side lengths, and is the angle opposite side .
By applying the appropriate trigonometric formula based on the information you have about the triangle, you can calculate the measure of angle .
