Given:
The number is -6.
To find:
The inverse with respect to addition of the given number.
Solution:
We need to find the additive inverse of -6, to get the inverse with respect to addition of -6.
We know that, the sum of a number and its additive inverse is 0.
Let the additive inverse of -6 be x. Then,
Adding 6 on both sides, we get
Therefore, the inverse with respect to addition of -6 is 6.
Answer:
22 sides
Step-by-step explanation:
The expression to find an interior angle of a polygon is:
The expression to find an exterior angle of a polygon is:
Please note that "n" represents the number of sides the polygon has.
We can use these two expressions to set up an equation.
Multiply both sides by "n":
Now, distribute:
Divide both sides by 10:
Add 36 to both sides:
Divide both sides by 18:
The polygon has 22 sides
