a pentagon has angles that measure 105 140 95 120 and m what is m
To find the measure of the missing angle, we need to use the fact that the sum of the interior angles of a pentagon is always 540 degrees.
We can find the missing angle by subtracting the sum of the known angles from 540.
Sum of known angles = 105 + 140 + 95 + 120 = 460 degrees
Missing angle = 540 - 460 = 80 degrees
Therefore, the missing angle measures 80 degrees.
