Element x is a radioactive isotope such that every 26 years , its mass decreases by half. Given that the initial mass of a sample of element X is 680 grams, how much of the element would remain after 19 years, to the nearest whole number?

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.
