1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula 
to find the distance from point 
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
Answer: 
.
For this case we have:
The area of the piece of fabric is given by 
Where
Substituting in the formula of the area we have:
Thus, the area of the piece of fabric is given by:
Answer:
Answer:
D
Step-by-step explanation:
Here, we want to get the value of x;
To get this, we simply use one of the circle angle and arc properties
Mathematically;
arc MN = 2 * arc MLN
3x + 22 = 134/2
That will be;
3x + 22 = 67
3x = 67-22
3x = 45
x = 45/3
x = 15
