Can someone me right now.

quadrilateral rstu, diagonals su and rt intersect at point v.

rstu is a parallelogram. if m∠tuv = 78° and m∠tvu = 54°, explain how you can find the measure of ∠srv. show all steps of your work, and refer to any properties of triangles, parallelograms, or triangle congruency theorems as necessary to justify your response.
