<u>Step 1: Define</u>
We are given a 5-sided polygon (irregular pentagon)
n = 5
<u>Step 2: Find Sum</u>
- Substitute in <em>n</em> [Sum of Angles]: 180(5 - 2)°

- Multiply: 540°
Answer:
There is a 20% probablity that the marble will be green :)
Step-by-step explanation:
- There are a total of 10 marbles in the bag. 4 red+4 blue+ 2green=10
- There are two green marbles out of the 10 marbles. 2/10
- 2 divided by 10 is .20 or 20%
- Therefore, there is a 20% probability that the marble will be green.
Answer:
5 feet & 15 feet
Step-by-step explanation:
<em>The question is to find the lengths of 2 sides of the rectangle</em>.
<u>Solution:</u>
Let shorter side be "x"
Let longer side be "y"
From the question, we can write:
y = 3x
also
y - x = 10
Now, putting the first on second equation, we get:
y - x = 10
3x - x = 10
2x = 10
x = 10/2 = 5
Now, y = 3x, y = 3(5) = 15
So we can say the lengths of 2 sides of the rectangle is 5 feet & 15 feet
