Given polygon BRAIN is similar to polygon POWEQalculate the value of WE, BR, and EQ

OpenStudy (anonymous):

A. WE = 5, BR = 11.25, EQ = 7 B. WE = 11.25, BR = 5, EQ = 7 C. WE = 5, BR = 7, EQ = 11.25 D. WE = 7, BR = 11.25, EQ = 5

OpenStudy (aripotta):

i'm getting warnings from doing your work for you lol. so we have to do this together. find the ratio by finding two corresponding sides that have just numbers (BN and PQ) and divide them

OpenStudy (anonymous):

so 10/4 = 2.5 ?

OpenStudy (anonymous):

2:5

OpenStudy (aripotta):

that's not the ratio. it's 2.5:1

OpenStudy (anonymous):

ugh .. alright well now that that's cleared up , what step is next ?

OpenStudy (anonymous):

still here ?

OpenStudy (aripotta):

we have to find WE. WE = 2x + 1 which is similar to AI, 12.5

OpenStudy (anonymous):

i am so confused

OpenStudy (aripotta):

so divide 12.5 by 2.5 to get 5. so WE should = 5. so 2x + 1 = 5. solve for x

OpenStudy (anonymous):

so D ?

OpenStudy (aripotta):

no, we already established that WE = 5, so the answer would be either A or C

OpenStudy (aripotta):

do you understand what i'm saying? or...?

OpenStudy (anonymous):

i think it would be A

OpenStudy (aripotta):

yes it is. sorry if i didn't explain it right. i guess you didn't need to solve for x, just use the ratio :/

OpenStudy (anonymous):

its all good , i think you did a very good job ! you did your best and you took your time out of the day to try and help me ! thanks very much , i appreciate it ! (:

OpenStudy (aripotta):
