Find the measure of one interior angle in each regular polygon. Plz

108°

Step-by-step explanation:

If regular polygon has n sides, then each interior angle = 180° - (360/n)°.

When n = 5, interior angle = 180° - (360/5)° = 108°

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
