625 people attended at least one play.
in the given question number of people who attended annual play 1 were=457 and number of people who attended annual play 2 = 372
the people who attended both were 104. now we can say number of persons who attended the play 1 only = 457-104 = 357
and number of people who attended play 2 only = 372-104 =268
therefor the people who attended at least one play = 357+268 = 625
so the answer is 625 people.
the measure of the other two vertical angles is 65°.
the measure of supplementary angles is 180°. therefore, as two of the vertical angles equate to 115°, their supplements must create a total sum of 180 when combined. 180-115=65
