We know that AB is perpendicular to CD. (that was given)
Perpendicular angles are 90 degrees because two straight lines (180) crossed make 4 90 degree angles.
180+180=360
90*4=360 See the similarities?
7x+6= 90 degrees
Subtract 6 on both sides.
7x=84
Divide both sides by 7.
x=12
"B" is the correct answer.
I hope this helps!

Answer:
The second set.
Step-by-step explanation:
Consider the first set of ordered pairs.
For an increase of 9 is the x-values the y values increases by 1.
In the case of the second set the increase in y values compared with increase in y values is different:
x = 2-0 = 2, y = 10- 0 = 10. That is 5 units of y for every unit of x.
x = 5-2 = 3, y = 13-10 = 3. That is 1 unit of y for every 1 unit of x.
send the decimals so I can help!
It would be A because 10,724 minus 1029 equals 9,695
Answer:
Here are the steps to find the volume.
Step-by-step explanation:
- Volume = length x width x height.
- You only need to know one side to figure out the volume of a cube.
- The units of measure for volume are cubic units.
- Volume is in three-dimensions.
- You can multiply the sides in any order.
- Which side you call length, width, or height doesn't matter.
