Approximately how many degrees are in the measure of an interior angle of a regular seven sided polygon

kramer

<h3>Resolution - Explanation</h3>

Square root is a real number x multiplied by itself - which results in a perfect value, where it is possible to calculate the real proof (which is the square root).

Given the expression, $\large \sf \sqrt{\dfrac{1}{x^{2} } } \cdot \sqrt{\dfrac{x^{2} }{81} }$ , first step: we will calculate the root of the numerator and denominator of this fraction:
