Use the Law of Detachment to write a valid conclusion for the given information.
1.If two angles are supplementary, then their measures have a sum of 180.
2.Angle X and Angle Y are supplementary.
-What do they mean when they ask me to write a valid conclusion?
The law of detachment, better known as Modus Ponens, can be expressed as p=>q, or if p is true, then q must be true.
p=it does not rain
q=I will go outside
If I say
If it does not rain, then I will go outside.
And if today it does not rain, a valid conclusion will be I will go outside.
If it does not rain today, I do not have a valid conclusion.
See if you can draw a valid conclusion from the given statements 1 and 2.
