$\begingroup$ Using that angle and radius 1, the answer is (one side of the pentagon) $ 2 \sin{\pi /5}$. My first answer was thinking on the other angle, eache intern angle of the pentagon is 108 degrees, that one is half of it, so is 54 degrees since the side is the adjacent to that i use $2 \cos{54}$, gives the same answer $\endgroup$ -

Math Mama Writes... Geometric Construction of the Regular Pentagon

Area A of a regular pentagon can be calculated from the formula: area = a² × √ (25 + 10√5) / 4, where a is a side of a regular pentagon. Also, you can find the area having the circumscribed circle radius: area = 5R² × √ [ (5 + √5)/2] / 4, where R is the circumcircle radius.

Inscribing a regular pentagon in a circle - and proving it Scott E. Brodie Constructions by straight-edge and compass of several regular polygons - the equilateral triangle, square, hexagon, and octagon, are familiar. Indeed, the construction of an equilateral triangle is the very first proposition in Euclid's Elements (I.1).
