The measure of minor arc is 108°
Pentagon:
A pentagon is a geometrical shape, which has five sides and five angles. Here, “Penta” denotes five and “gon” denotes angle.
If a pentagon is regular, then all the sides are equal in length, and five angles are of equal measures. If the pentagon does not have equal side length and angle measure, then it is known as an irregular pentagon.
The sum of all the interior angles for a regular pentagon is 540°.
hence,
Value of each interior angle = 540°/5
= 108°
From figure,
we have to find ∠AED
we can see ∠AED is one of the internal angle of pentagon.
so,
∠AED = 108°
