Answer:
See below.
Step-by-step explanation:
The sum of the measures of the interior angles of an n-sided polygon is
(n - 2)180
A pentagon has 5 sides, so for a pentagon, n = 5.
(n - 2)180 = (5 - 2)180 = 3(180) = 540
The sum of the measures of the angles of a pentagon is 540.
You don't show the measures of the 4 angles that are known, so to answer the question, add the 4 given measures and subtract the sum from 540.

Answer:
Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
Step-by-step explanation:
To find the average membership in Gym A is simple. To get 72 to 124, we need to subtract them getting 52, this is the same for the other weeks. So, Gym A gets 52 members per week. Gym B is a bit more complex, each week has to be constant so subtract 204 by 80 and you get 124. Divide 124 by 2 because the difference between Week 1 to 3 is 2. Then we get 62 some Gym B gets 62 average members per week. Hope this helps. Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
The expression that represents the density is D = h^2 - 4h + 20/pi h^2
