Answer:

2x + 120 = 180 (being co interior angle)

or, 2x = 180 - 120

or, 2x = 60

or, x = 60/2

or, x = 30

therefore 2x = 2* x = 2* 30= 60

Two parallel lines are there
Sum of angles =180
Add them
(2X-20)+(3X+10)=180
5X-10=180
5X=180+10
5X=190
X=190/5
X=38

The perimeter of a rectangle is 34 units and its width is 6.5 units
IgorC [24]
Since you technically didn't ask for anything to be solved for, this problem is now solved. Since these types of problems are normally solving for legnth if width is given and vice versa, I will solve for legnth.

perimiter=legnth+legnth+width+width or
p=l+l+w+w
p=2l+2w
subsitute w=6.5 and p=34
34=2l+2(6.5)
34=2l+13
subtract 13 from both sides
21=2l
divide by 2
10.5=l

legnth=10.5 units

Last option is none of the above
BigorU [14]

Answer:

A and B

Step-by-step explanation:

When rotating a point (or any shape around a certain point), none of the diameters of the shape will change. So for example, with this circle, when you rotate it around a point, the radius and circumference will not change because it has just rotated. It wont be on the x-axis though because point P is not on the x-axis an it is being rotated 180 degrees about point P. Just know that when you are rotating, nothing about the shape changes, all angles or measurements will be the same, it is just moving to a different place.

Hope this helped ^-^
