Polygon CCC has an area of 777 square units. Jennie drew a scaled version of Polygon CCC and labeled it Polygon DDD. Polygon DDD has an area of 282828 square units. What scale factor did Jennie use to go from Polygon CCC to Polygon DDD?

step-by-step explanation:

i need more details sorry

step-by-step explanation:

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

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
