Which expression is equivalent to

What is the length of the missing leg in this right triangle? 18 mm 24 mm 26 mm 32 mm

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.

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.
