Question

Geometry, please help!

Answer 1

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.

Answer 2

Which of the following changes should she make to the dimensions to correct her error?

a. change the length of side RP to 3 feet

b. change the length of side CA to 5 feet

c. change the length of side RP to 8 feet

d. change the length of side CA to 6 feet

Answer 3

hero!!

Answer 4

@LoveToDance, Have you computed the ratios of the corresponding sides yet?

Answer 5

No, I'm not sure how to solve this.

Answer 6

Hint:
To find the ratios of the corresponding sides of two similar triangles, notice that:
RP corresponds to CA
PQ corresponds to AB
QR corresponds to BC

Next compute:

\(\frac{RP}{CA}\)

\(\frac{PQ}{AB}\)

\(\frac{QR}{BC}\)

Answer 7

@Hero Is it B? (change the length of side CA to 5 feet)

Answer 8

How did you figure it out?

Answer 9

I used ratios haha, thanks!
