i'm very confused about this topic, help me please

\fDetermine Z VYX. Do not include units in your final answer! Z U 190\fAdrianna and Madi each calculated the measure of the external angles of a regular 40-sided polygon. Adrianna's Solution Madi's Solution In a regular polygon with n sides, the extarnal anagles Determine the interior angle, x, and subtract that value sum 360. from 180: This means that if x represents the external angle: (180) (22 - 2) X = 3600 12 - 2 (1809)(40 - 2) 3609 40 - 2 (1809) (38) 3609 * = 40 X = 38 68409 X = 9.4736842105260 40 x = 1710 Thus, the measure of the external angle is: 180 - 1710 = 90 Who is correct? Select one: O a. Only Madi is correct. O b. Adrianna and Madi are both correct. O c. Only Adrianna is correct. O d. Neither Adrianna nor Madi is correct
