In a trapezoid, all angles will add up to 360 degrees. And, that angles T and R will be equal, and angles P and A will also be equal. Therefore, we can double what we have for t and p, add those together, and set them equal to 360 degrees.
2(4x + 12) + 2(2x) = 360
8x + 24 + 4x = 360
12x + 24 = 360
12x = 336
x = 28
The correct answer is C. 28.
Hope this helps!! :)
Answer:
Temperature is measured in units of temperature.
In SI units, it is K (degrees Kelvin).
In CGS units, it is °C (degrees Celsius)
In English units, it is °F (degrees Fahrenheit)
Therefore the mean and standard deviation will be measured in the selected units for temperature.

Option C:
The measure of arc CD is 40°.
Solution:
Given data:
m∠X = 11° and m(arc AB) = 18°
To find the measure of arc CD:
We know that,
<em>Angle formed by two intersecting secants outside the circle is equal to half of the difference between the intercepted arcs.</em>
Multiply by 2 on both sides.
22° = arc CD - 18°
Add 18° from both sides.
40° = arc CD
Switch the sides.
arc CD = 40°
Hence the measure of arc CD is 40°.
Option B is the correct answer.
19.2 is the answer. you add them up then estimate to find you answer.
