Hi, yeah, so I have two problems that are preventing me from continuing on in my lessons and they're really important however I cannot find information as to how to solve them or any program that could help, I turn to you in dire times. Both problems need x and y solved. Which equals 4 total answers. The problems appear simple in nature.... so. What the hell? I'll post both pictures that ask to solve for the two variables.

._. I'm not impressed with myself either, I don't know. Usually in the Geometry CR, I've never met anything that just wasn't taught in the lessons, but. On the post test, come to find out these questions are on here with *NO* explanation as to how to solve them. I mean, I googled a couple of things like; "Similar Triangles" and such, but to no avail.

>> No.5885562

The bars on the sides imply that the two lengths are equal. Solve for x and y.

Yes.

Those short lines through the middle of the segments tell you which ones are equal (and hence which length values are equal).

it's an euclidean geometry type problem.

there is a proportionality between lenghts of the segments since they are parallels cut by 2 transversals.
