Converse: If two angles with the same measure, they are not congruent.
Inverse: If two angles are not congruent, then they do not have the same measure.
Contrapositive: If two angles do not have the same measure, then they are not congruent.
The answer is 74,000 years.

amount remaining, where n is a number of half-lives.
<span>Decimal amount remaining is 0.00012 (= 0.012%). Let's calculate number
of half-lives.</span>
<span>
</span>
⇒
⇒
⇒ n ≈ 13
<span>
Now we know that number of half-lives is 13.</span>
Number of half-lives is quotient of total time elapsed and length of
half-life.<span>
<span>So, total time elapsed is a product of length of
half-life (5,730 years) and number of half-lives (13). Since 5,730 years × 13 =
74,490 years, then the person died 74,000 years ago (rounded to the nearest thousand).</span></span>
