Answer:
24. A.
25. B.
Step-by-step explanation:
n = number of corners or vertices (and their also the number of sides) of the polygon.
24.
(n-2)×180° is the sum of all angles in a polygon with n sides.
25.
a convex polygon is a closed figure where all its interior angles are less than 180° and the vertices are pointing outwards.
the sum of interior angles of a convex polygon with 'n' sides is given (as verified by 24.) by the formula (n-2)×180°.
so,
S = (n-2)×180
S/180 = n - 2
S/180 + 2 = n
