You are correct. The answer is D 5:3
Answer:
C, none of them are equivalent
BECAUSE
For A, the -4q should be positive 4q to apply
For B, the 2q when distributing with the parentheses should be negative 2q to work with the expression above
Hope this helps!
We know that
The exterior angle measures of a polygon must add up to 360°,
therefore
360°/72°=5 exterior angles
so
5 exterior angles, would mean 5 interior angles and therefore 5 sides to the polygon
The exterior angle and the interior angle of any polygon are supplementary and must add up to 180°.
exterior angle+interior angle=180°
interior angle=180°-exterior angle
interior angle=180°−72°-------> 108°
Each interior angle is 108°
The sum of the interior angles would be
5*108°=540°
the answer is
540°
