x^2 \ \textgreater \  49 \\  \\ 
x_{1,2} =  \pm \sqrt{49}  = \pm 7 \\  \\ 
\boxed{x \in (-\infty, ~-7)\bigcup (7,~ +\infty) }

Solving the inequality above,
                                       x² > 49
Take the square roots from both sides of the inequality,
                                     x > 7   and x < -7
Therefore, the solutions to the inequality above are shown below
                                            (-∞ , -7] ∪ [7 , +∞)

Find the measure of one interior angle for the following regular polygon ​
kipiarov [429]

Answer:

144 degrees

Step-by-step explanation:

We can use the formula (n-2)(180), where n = number of sides, to find the sum of all the interior angles in the decagon. Since a decagon has 10 sides:

(n-2)(180) = ?

(10-2)(180) = ?

(8)(180) = 1440.

Now, to find one interior angle in the decagon, divide 1440 by the number sides in our polygon (10).

1,440/10 = 144

               = <u>144 degrees</u>
