Segment AO=2x+1 and segment OC=5x-2. If segment BC is 4, what is the perimeter of triangle obc?

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Someone answer this check out the image!

I’m still confused on how to work the percentages
