We can work out the length we are looking for by taking the difference \displaystyle a-b of the sides \displaystyle a and \displaystyle b in the triangles below.
If we take the tangent of the given angle in each triangle, we easily obtain \displaystyle a and \displaystyle b.
Hence,
\displaystyle x = a-b = \sqrt{3}-1\,\textrm{.} |
