In this series, the Argentinian Op'Art artist Juli Le Parc, uses his famous 14 color palette to let mathematics mix them in a fixed but rather randomly looking way. Let's investigate what is happening there!

Find out the distance, in $ cm$, between point $A$ and $ G$. Give your answer with one decimal place.

Seja $\alpha \in \left [ \frac{\pi }{2}, \frac{3\pi }{2} \right ]$, tal que $sen\alpha =\frac{\sqrt{5}}{5}$ Determina o valor de $tg\left ( \pi +\alpha \right )\times cos\left ( \frac{11\pi }{2}+\alpha \right )+sen\left ( -\frac{\pi }{2}-\alpha \right )$. Apresenta o resultado arredondado às centésimas.
