This is a trick question. DFG is the isosceles right triangle so DGF=FDG=45 degrees. We have triangle DEF congruent to DGF, side-side-side. So EDG=90 degrees, so ADG=90 (they're supplementary). That's the measure of the arc AG.
Answer: 90 degrees
Both diameter and height are scaled by 2.5.
Area is measured in squared units ( square centimetres).
Square the scale factor:
2.5^2 = 6.25
Multiply the area of the smaller vase by the scale:
2826 x 6.25 = 17,662.5 square cm.

14 = 31.7 - 3x
-17.7 = -3x <---- I subtracted 31.7 from both sides
5.9 = x <---- I divided both sides by -3
