Answer:
9% = 450
10% = 500
8% = 400
Step-by-step explanation:
The <em><u>correct answer</u></em> is:
A line of reflection would need to be drawn as a line that bisects a vertex angle of the pentagon.
Explanation:
A line that bisects a vertex angle of a pentagon will be a line of symmetry within the pentagon. The pentagon can be "folded" through this line into two equal halves.
This imaginary line represents the center of the pentagon. A reflection through this line will carry the pentagon onto itself. This is due to the definition of line symmetry:
"A set of points has line symmetry if and only if there is a line, l, such that the reflection through l of each point in the set is also a point in the set."
Additionally, for any regular polygon, the number of lines of symmetry equals the number of sides.
This means that this line can be through any vertex angle of the polygon.
The two given angles when added together needs to equal 180 degrees ( straight line)
X + 34 + 2x + 2 = 180
Combine like terms:
3x +36 = 180
Subtract 36 from both sides:
3x = 144
Divide both sides by 3:
X = 48
The answer is B.
Answer:
B
Step-by-step explanation:
√((-20)²+21²)=√(400+441)=√841=29
cos θ=-20/29
sec θ=-29/20
Answer:
450 gallons
Step-by-step explanation:
It will hold 450 gallons since if it’s the same size and pour it in it will not change the amount of water you have.
