11. The two angles are vertical angles, which mean they are equal to each other.

14x - 5 = 13x

Add 5 to both sides:

14x = 13x + 5

Subtract 13x from both sides:

x = 5

12.  The two angles are supplementary and when added together need to equal 180 degrees.

5x -20 + 3x = 180

Combine like terms:

8x -20 = 180

Add 20 to both sides:

8x = 200

Divide both sides by 8:

x = 200 /8

x = 25

​how many meters is the circumference of a circle with a radius of 20 cm?
Harman [31]
First find the circumference of the circle.
Circumference: 2 \pi r

Plug in 20 for the radius (r).
2 \pi20 = 125.66 

The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.

Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26

The circle's circumference is 1.26 meters.
