**Henry**, Tuesday, September 21, 2010 at 11:25pmX White shirts,

Y yellow shirts,

X + Y = 21 Shirts.

Y = 21 - X

Cost = 10.95x + 13.5y = 275.85,

Substitute 21 - X for Y

10.95x + 13.5(21 - x) = 275.85,

10.95x + 283.5 - 13.5x = 275.85,

-2.55x = -7.65

x = 3 = White shirts,

3 + Y = 21

y = 18 Yellow shirts.

x = 1st angle,

(2x - 3) = 2nd angle,

x + (2x - 3) = 180 Deg.

2x - 3 = 180,

3x = 183,

x = 61 Deg. = Smaller angle,

(2x - 3) = 2 * 61 - 3 = 119 Deg. =

Larger angle.
