One angle of a pentagon is 124. The others are equal to each other . Find them

Answer 1

one right turn around outside = 180 - 124 = 56
the sum of all the right turns has to be 360
so sum of other 4 = 360 - 56 = 304
so each is 304/4 = 76
and 180 - 76 = 104

Answer 2

the angles of a pentagon add up to 3*180 = 540 degrees.
So if the other angles are x degrees,
4x+124 = 540
x = 104
