Apiece of carpet is 8 feet wide and 12 feet long. the carpet needs to be reduced by a scale factor so that the reduced carpet is 2 feet wide. what is the area of the reduced carpet

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

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
