If the question refers to the total angle on a straight line then the angles are adjacent and supplementary - the angles total 180° .
Well, they're called vertically adjacent angles. They have the property that they are supplementary, because the non-adjacent sides form a straight line.
Sum of adjacent angles on a straight line.
Each angle is 180/5 = 36 degrees
they form a straight line

Sum of adjacent angles on a straight line.
Any angles A, B where A + B = 180 deg.
Supplementary angles.
180o or a line
Because that is what a straight line (or straight angle) is.
Thereby forming a straight line.
A pair of angels in a straight line formed by a line or half-line meeting it is called adjacent angels. Adjacent angels will add up to 180°.
