By AA Similarity, the given two triangles are similar. Theorem 7.10 states that if two triangles are similar, the lengths of corresponding medians are proportional to the lengths of corresponding sides. We know that the segments marked x and 21 are medians because they intersect the opposite side at its midpoint. 7KHUHIRUH $16:(5 9 62/87,21
