ahh they're not online. why do you think it is D?
anonymous
  • anonymous
I think it is D because I looked up the definitions for similarity theorem and similarity postulate. I already knew it was angle angle because means that the triangles have two of their angles equal and parallel.
anonymous
  • anonymous
AA means they have to be in two different triangle or parallel, but always equal.

A scale factor represents the ratio of corresponding sides in similar figures. (scale factor)^2 => area ratio (scale factor)^3 => volume ratio √( 2023/1183) = 17 / 13 (17/13)^3 = 4913 / 2197 4913 / 2197 = 2333 / x x = 1043.27 in^3

All the corresponding angles are equal so they must be similar right \[\large{\cfrac{Ar[ABE]}{Ar[CED]} = [\cfrac{BE}{CE}]^2}\] \[\frac{ 68 }{ 425 }=\frac{ 100 }{ x^2 }\] \[68x^2=42500\] \[x^2=625\] \[x=25\]

anonymous

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above)... And there are eight angles... So, the measure of the interior angle of a regular octagon is 135 degrees.
