Answer:
The rectangle ABCD and the congruent angles are shown in the diagram below.
We know that T is a midpoint.
That gives us the length of TD = length of TB, also TA = TC
Look for triangle ATD and BTC, we have so far that:
TD = TB and TA = TC
∠DAT = ∠BCT (properties of alternate angles)
∠ATD = ∠BTC (properties of opposite angles)
By the postulate SAS (Side Angle Side) we can deduce that AD = BC
Answer: TB = TD (Fourth option)

Answer:
The correct answer is (4) a ratio variable
Step-by-step explanation:
Nominal, ordinal, interval, or ratio data are the four fundamental levels of measurement scales that are used to capture data.
Nominal scales are used for labeling variables, without any quantitative value.
Ordinal the order of the values is what is significant, but the differences between each one is not really known.
Interval we know both, the order and the exact differences between the values
Ratio they have the order, the exact value between units, and have an absolute zero
In this case, the concentration of DDT (C14H9Cl5), in milligrams per liter is a RATIO, because it has order, the exact value between units, and have an absolute zero

23.8
