The image shown has two triangles sharing a vertex: There are two triangles labeled RST and TUV with a common vertex T. In triangle RST, angle SRT is labeled as y, and angle RST is labeled as 55 degrees. In triangle TUV, angle TUV is labeled as 55 degrees. What is the measure of ∠TVU, and why? (4 points) y, because Triangle RST is similar to triangle VUT y over 2, because Triangle RST is congruent to triangle VUT y + 55 degrees, because Triangle RST is similar to triangle TUV 125 degrees − y, because Triangle RST is congruent to triangle TUV
