Now the triangles formed by the star are isosceles, so the other angle at the base measures
\n\n
Thus, the measure of an angle at the vertex will be
\n\n
Then, each angle at the vertices of star has a measure of
\n\n
Therefore, the sum of all the angle at five vertices of the star
\n\n
Hence, the required answer is .
