Answer:
We can't prove this with the SAS postulate.
Step-by-step explanation:
SAS means that two sides and the angle between those two sides are equal.
Side Angle Side (SAS)
That's why we can't prove this with the SAS postulate.
Using proportions, it is found that the speed of the runners are of 16 mph and of 20 mph.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
After 30 minutes, the runners are 2 miles apart, hence the second runner is 4 miles per hour faster than the second, that is:
.
The first runner's speed is 4/5 of the speed of the second runner, hence:





Hence, the speed of the runners are of 16 mph and of 20 mph.

0.555x91,000=50,505 are under 40
91,000-50,505=40,495 are over 40
Answer:
A = 16π cm²
Step-by-step explanation:
We require to find the radius r
Given circumference C = 8π , then
2πr = 8π ( divide both sides by 2π )
r = 4 , then
A = πr² = π × 4² = 16π cm²
