Sasha and Chloe are throwing darts at a map of the complex plane. Sasha's dart lands on the point $15+8i$. Chloe's dart lands on the point $3-4i$. How much closer to the origin is Chloe's dart compared to Sasha's?
The distance from the origin to any point $a+bi$ is given by the formula $|a+bi| = \sqrt{a^2+b^2}$. So, the distance from the origin to Sasha's dart is $|15+8i| = \sqrt{15^2+8^2} = \sqrt{225+64} = \sqrt{289} = 17$. And the distance from the origin to Chloe's dart is $|3-4i| = \sqrt{3^2+(-4)^2} = \sqrt{9+16} = \sqrt{25} = 5$. Therefore, Chloe's dart is $17-5 = 12$ units closer to the origin than Sasha's.
