Arecipe for cake needs 3/4 of a cup of milk. you are making 1/2 of the recipe . how much milk do you need?

Can somebody me out with this question

1. what is the measure of ∠abc? what is the measure of ∠abd?

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.
