Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. two angles measuring 180 are supplementary. question 2 options: two angles not measuring 180 are not supplementary. true two angles not measuring 180 are supplementary. false non-supplementary angles are two angles not measuring 180. true more than two angles measuring 180 are non-supplementary. true

Given a statement like "if P, then Q", the contrapositive statement is "if not Q, then not P".

A statement and its contrapositive are logically equivalent, so they are either both true or both false.

So, since the original statement is the definition of supplementary, it is true, and so is its contrapositive, which is

"if the sum of two angles isn't 180, they are not supplementary"

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
