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.

Answer:
A) 58.5
Step-by-step explanation:
Pythagorean theorem: A squared + B squared = C squared
32 squared + 49 squared = 3425
Find the square root of 3425.
√ 3425 = 58.5234
Round to nearest tenth
58.5
