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...
