Given: parallelogram ABCD with AB = 2x, CD = 3y + 4, BC = x + 7, and AD = 2y. Find the lengths of the sides of the parallelogram.

50 ! pls ! 12.  building codes regulate the steepness of stairs. homes must have steps that are at least 13 inches wide for each 8 inches that they rise.

a. discuss how to find the slope of the stairs.
b. describe how changing the width or height affects the steepness of the stairs.

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.

Two parallel lines are crossed by a transversal. what is the value of x? x = 40 x = 70 x = 110 x = 130
