Question

An architect planned to construct two similar stone pyramid structures in a park. The figure below shows the front view of the pyramids in her plan, but there is an error in the dimensions:

Which of the following changes should she make to the length of side CA to correct her error?
Select one:
a. Change the length of side CA to 6 feet
b. Change the length of side CA to 3 feet
c. Change the length of side CA to 5 feet
d. Change the length of side CA to 8 feet

Answer 1

this is an incomplete question it doesn't have any of the complete dimensions what is the measurements of sides?

Answer 2

This is all I got for it. @Darby.Allen

Answer 3

Do you see the image I attached to this when I posted it?

Answer 4

HINT: look at the ratios... similar means they should be the same, but are they all the same? calculate them

Answer 5

I don't really understand it. Geometry is my worst. ): @inkyvoyd

Answer 6

*side lengths... what happens if you look at corresponding parts of similar triangles?

Answer 7

It would mean that they're congruent, right? @inkyvoyd

Answer 8

nope, similar doesn't necessarily mean congruent. Similar just means that they're proportional to each other. Think of a map. Small maps scale everything down so it fits, but if a state border is twice as much as another state border in real life, it'll still be twice as small on the map - everything shrinks the same... if you're looking at two "triangles", and you know they are similar, think of the maps. One side length might not be double another, but if the ratio of all the corresponding side lengths should be the same, no?

Answer 9

the answer is b
