Answer 1

Answer:

Sin, Cos and Tan

Step-by-step explanation:

2. The sine of the angle = the length of the opposite side. the length of the hypotenuse.
3. The sine of the angle = the length of the opposite side. the length of the hypotenuse.The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
4. The sine of the angle = the length of the opposite side. the length of the hypotenuse.The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.The tangent of the angle = the length of the opposite side. the length of the adjacent side.
