Step-by-step explanation:

The adjoining star contains a regular pentagon.

So, sum of interior angles =(5−2)×180

o

=540

o

In regular polygon, each angle is of same measure

∴ Each interior angle measures 108

o

It's supplementary angle measures 180

o

−108

o

=72

o

Now the triangles formed by the star are isosceles, so the othere angle at the base measures 72

o

∴ measure of an angle at the vertex will be 180

o

−72

o

−72

o

=36

o

∴ Each angle at the vertices of star has a measure of 36

o

.

Thus, the sum of all the angle at five vertices of the star =5×36

o

=180

o

Hence, the answer is 180

plzzzz mark in the brainlist...
