Since the degree given to you is 25 you can identify the three sides. The longest side opposite to the 90 degree angle is the "hypotenuse", the shortest side is the "opposite", and the side that is 120 m is the "adjacent".
Once you know the names of the three sides you just have to remember SoaCahToa. Meaning Sin is opposite over adjacent, Cosin is adjacent over hypotenuse, and Tangent is opposite over adjacent. The two sides you were given are x (the hypotenuse) and 120 (the adjacent) so you use Cosin.
Answer:
We all experience inequality. Never have I known it to be enjoyable.
Step-by-step explanation:
Nobody is created equally and that's the cold hard truth. Each of us is born into a different story/background, with a unique set of characteristics. Often I've known inequality to lead to envy, vendettas, and insecurity.
The reference angle is the angle made with the x-axis. For two points to have the same reference angle, they would need to have the same absolute value of their tangents = y/x.
For the first pair of points: the first point has a tangent value of 1/sqrt(3), while the second has a tangent value of sqrt(3), so these are not identical.
For the second pair of points: the first point has a tangent value of -sqrt(3), while the second has a tangent value of -1/sqrt(3), so these are
not identical.
For the third pair of points: the first point has a tangent value of sqrt(3), while the second also has a tangent value of sqrt(3), so these have the same reference angle.
For the fourth pair of points: the first point has a tangent value of
1/sqrt(3), while the second has a tangent value of sqrt(3), so these are
not identical.
So the only correct answer is the third choice.
The answer is,
