Answer:
The answer is 20 degrees
Step-by-step explanation:
A trapezoid is a quadrilateral with four angles and the sum of the four angles is 360 degrees.
Britton rotated the trapezoid ABCD 180º, but we were not told that he tampered with the angles size or shape, we can now agree that it is still the same trapezoid that was rotated without any alterations in angles, size and shape.
Since we've been given that the angle B is 20º, and the measurement was not altered when rotating the trapezoid. Therefore the angle B' will also be 20º.
I hope this helps.
If B is the top center then all three are true

Answer:

563 - (563x0.25) = 422.25 -> 422
16
422 -(422x0.25) = 316.5 -> 317
20
317 - (317x0.25) = 237.75 -> 238
24
238 - (238x0.25) = 178.5 -> 179
28 (continue the step by step process)
134.25 -> 134
32
100.5 -> 101
36
75.75 -> 76

Step-by-step explanation:
the time interval has to keep skipping by four hours because the medicine is filtered in that amount of time.
The multiplying by 0.25 part must be done first in order to show how much the kidney has filtered.
after this, you need to subtract that from how many milligrams of medicine are left in your system
note that if you do not subtract, you will only be showing how much the kidney has filtered. the question asks for how much is left in the SYSTEM overall, so subtracting is quite necessary to completely answer the question.
I hope this helped.
