Two complementary angles are congruent. Which equation gives the measure in degrees, d, of each angle?

2d=90
d=45
complementary angles add up to 90 degrees. If the two angles are congruent, it means that both angles have the same measurements

$x^2+8x=-1\\
x^2+8x+16-16=-1\\
(x+4)^2=15\\
x+4=\sqrt{15} \vee x+4=-\sqrt{15}\\
x=-4+\sqrt{15} \vee x=-4-\sqrt{15}$

First take 10,000 * 2 = 20,000, because each of the 10,000 tickets cost 2 dollars.

3000(1/20000) + 1000(3/20000) + 500(5/20000) + 100(20/10000) = 10500/20000 = .525

Thus, each ticket is worth 52.5 cents.

Hope it helps <3
