a) Proof by contradiction is different from traditional proof as it accepts a single example showing that a statement is false, instead of having the need to derive a general relationship for all input values.
b) The statement is true by contradiction as the sum of the measures is of 160º, and not 180º.
<h3>What are supplementary angles?</h3>
Two angles are called supplementary angles if the sum of their measures has a value of 180º.
The measures of the angles in this problem are given as follows:
Then the sum of the measures of this angles is given as follows:
90 + 70 = 160º.
Which is a different sum of 160º, confirming the statement that the angles are not supplementary by contradiction.

50% or 32/64 because 32 is half of 64
Answer:
a) 72
b) $259.2
Step-by-step explanation:
A- The bus travels 40 miles on 8 gallons of gasoline. The bus is traveling 360 miles in total.
360/40= 9
9*8= 72
B- $3.60 per gallon and 72 gallons in total.
3.60*72=259.2
$259.2
