Solve [1+sinpi/10+icospi/10/1+sinfrac{pi{10}-icospi/10}]10

$$[ \frac { 1 + \sin \frac { \pi } { 10 } + i \cos \frac { \pi } { 10 } } { 1 + \sin \frac { \pi } { 10 } - i \cos \frac { \pi } { 10 } } ] 10$$

Evaluate

$$\frac{5\left(-\sqrt{5}-7+i\sqrt{2\left(5\sqrt{5}+25\right)}\right)\left(-3i\sqrt{2\left(\sqrt{5}+5\right)}+\sqrt{5}-3\right)}{-9i\sqrt{2\left(\sqrt{5}+5\right)}+9\sqrt{5}+43}\approx 3.090169944+9.510565163i$$

Real Part

$$10\left(-Im(\frac{-3i\sqrt{2\left(\sqrt{5}+5\right)}+\sqrt{5}-3}{2\left(-9i\sqrt{2\left(\sqrt{5}+5\right)}+9\sqrt{5}+43\right)})\sqrt{2\left(5\sqrt{5}+25\right)}-\left(\sqrt{5}+7\right)Re(\frac{-3i\sqrt{2\left(\sqrt{5}+5\right)}+\sqrt{5}-3}{2\left(-9i\sqrt{2\left(\sqrt{5}+5\right)}+9\sqrt{5}+43\right)})\right)$$
