Answer:</h2>
The undefined term that is used to define an angle is:
Line.
<h2>
Step-by-step explanation:</h2>
Angle is formed with the help of two lines which are not parallel to each other and intersect at a point.
( Also, such two lines are known as a ray.
Since a ray is a line with one end point and the angle is formed with the help of 2 rays with the same starting or initial point )
From the diagram we may see how the angle is formed.
Hence, the answer is:
Line
Answer:
Terminal side in 2nd Quadrant
Only sin(x) & cosec(x) are positive in 2nd Quadrant

Perpendicular=5
Base=√(13²-5²)=√(169-25)=√144=√12²=12
Hypotenuse=13

5y = -3x + 7
y = -3/5x + 7/5
Parallel = same slope
y = -3/5x + b
3 = -3/5 + b, b = 18/5
Standard form: Ax + By = C
y = -3/5x + 18/5
-3/5x - y = -18/5
Multiply by -5
Solution: 3x + 5y = 18
