Is the following statement always, sometimes, or never true?

“the supplement of an acute angle is an obtuse angle.”

explain your answer.

answer:

the statement is always true because the sum of the two angles must be 180 degrees to be supplementary. if the first angle is an acute angle, then it has a measure of less than 90 degrees. to sum 180 degrees, the second angle would need to be more than 90 degrees, making it an obtuse angle.
