Pls i will mark brainliest to first correct and explained answer

the image shown has two triangles sharing a vertex:
what is the measure of ∠tvu, and why?

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
