Since these are supplementary angles (two angles which sum to 180°) we can say:
4x+x=180 combine like terms on left side
5x=180 divide both sides by 5
x=36°
-- The person in the audience will either win tickets or not win tickets.
-- The probability of (either win tickets or not win tickets) is 100%.
-- (Probability of win tickets) plus (probability of not win tickets) = 100%.
-- If (probability of win tickets) is 15%, then the (probability of not win tickets)
is the other 85%.
