B. The answer would be B because inscribed means inside the circle. All the points in the angle touch the side of the circle.
Hope I could help!!!!!
Good luck!!!!
Answer:
1. 144⁰
2. 60⁰
Step-by-step explanation:
The formula to find the measure of the interior angles of a regular polygon is:
m< = (n - 2) • 180/n where n = the number of sides
For a decagon, there are 10 sides.
m< = (10-2) • 180/10 = 144°
A regular polygon/equilateral triangle is defined as having equal sides and angles.
Answer:
l=48, w=20
Step-by-step explanation:
Let the width of the pool be w feet, then the length will be:

The area of the pool is 960 square feet.
This means that:

Expand and rewrite in standard form to get:




Factor to get:


We discard the negative value because magnitude is positive.
This means

Y = a(1 - r)^t
Y = 8,000(1 - 0.06)^t
You can see a = 8,000
As the fish population starts at 8,000
Answer:
w= 9 3/4
Step-by-step explanation:
4 1/5 =21/5
13 19/20= 279/20
w+21/5 + 279/20
-21/5 -21/5
w+39/4
w=9 3/4
