x = 50

The angles shown are vertically opposite and thus equal

so 3x - 30 = 2(x + 10)

3x - 30 = 2x +20

subtract 2x from both sides

3x - 2x - 30 = 20

x - 30 = 20

add 30 to both sides

x = 20 + 30 = 50

The value of each winning ticket is an arithmetic series in which T (n) = -5 + 15n or $5 (3n-1). The first winner is 5 (3x1 - 1) = $10. The second winner is 5 (3x2 - 1) = $25. The tenth ticket wins $5 (3x10 - 1) = $5 (29) = $145.
