answers are 100 50 5 4

OpenStudy (cwrw238):

use this property of similar triangles: corresponding sides are in the same ratio

OpenStudy (cwrw238):

first you need to identify the corresponding sides

OpenStudy (anonymous):

PML is five times bigget and the corresponding side to x is PM, which is 2o, so you divide that by five and get 4. x=4.

OpenStudy (anonymous):

oh okay! thank yall!

OpenStudy (cwrw238):

x/20 = 2 / 10

OpenStudy (anonymous):

I said 20/x, which equals 10/2

OpenStudy (cwrw238):

yes - both equations give the correct answer

OpenStudy (anonymous):

True, I should've thought about that.

OpenStudy (cwrw238):
