The ratio of life expectancy to gestation period is greatest at point (A) A.
<h3>What is life expectancy?</h3>- Life expectancy is a statistical measure of how long an organism is expected to live based on its birth year, current age, and other demographic factors such as gender.
- The most commonly used metric is life expectancy at birth (LEB), which has two definitions.
To find the labeled points, which represent the animal for which the ratio of life expectancy to gestation period is greatest:
- The graph below shows life expectancy on the y-axis and gestation period on the x-axis.
- The life expectancy to gestation period ratio for point A is 7/22.5 = 14/45.
- For point B, the ratio is 8/45.
- Because the y coordinate is greater at Y than at X, which has the same x coordinate, we only consider the ratio at D, which is 10/51.
- Since 14/45 > 8/45, we only have to compare 14/45 and 10/51.
- So, 14 × 51 = 714 and 45 × 10 = 450.
- Then, 14/45 > 10/51.
Therefore, the ratio of life expectancy to gestation period is greatest at point (A) A.

we know that
(x+20)+∠1=180°-------> by supplementary angles
∠1=160°-x
∠1+∠2=180°--------> by supplementary angles
∠2=180-(160-x)-----> ∠2=20+x
∠2=80°------> by corresponding angles
so
20+x=80
x=80-20-------> x=60°
the answer is
60°
