Answer: 172.8°
Step-by-step explanation:
For a regular polynomial of N sides, the sum of all interior angles must be equal to:
Sum = (N - 2)*180°.
In this case we have N = 50
Then:
Sum = (50 - 2)*180° = 48*180°
Now, if all the 50 interior angles have the same measure, then the measure of each one will be equal to the quotient between the sum and the number of sides, this is:
Sum/50 = (48/50)*180° = 172.8°
Then the interior angles of a regular polygon of 50 sides is 172.8°

Answer:
-8, 7
Step-by-step explanation:
Set up an equation.
<em>x² + x = 56</em>
Set the equation equal to zero and factor.
<em>x² + x - 56 = 0</em>
<em>(x + 8)(x - 7) = 0</em>
Solve for x.
<em>x + 8 = 0</em>
<em>x = -8</em>
<em>x - 7 = 0</em>
<em>x = 7</em>
The possible x values are -8 and 7.
Answer:
An unknown variable by reversing the process used to form the original equation.
Step-by-step explanation:
The opposite process rule says to solve for - an unknown variable by reversing the process used to form the original equation.
If an equation indicates an operation such as addition, subtraction, multiplication, or division, solve for the unknown variable by using the opposite process.
For example:
Lets say we have to find
Here 25 is subtracted from both sides of the equation to isolate x.
we get x = 10
