Question

GIVE MEDAL

In ABC, AB = x, BC = y, and CA = 2x. A similarity transformation with a scale factor of 0.5 maps ABC to MNO, such that vertices M, N, and O correspond to A, B, and C, respectively. If OM = 5, what is AB?

AB = 2.5

AB = 10

AB = 5

AB = 1.25

AB = 2

Answer 1

if ab is x
ca is 2x
and CA corresponds to OM
what would you think the answer is?

Answer 2

e?

Answer 3

hint:OM is twice the length of AB

Answer 4

its b

Answer 5

right?

Answer 6

OM is twice the length of AB
so we know OM=5
5 is twice of what number?

Answer 7

ummm....

Answer 8

2.5?
idk xD
