PLEASE HELP, WILL MARK BRAINLIEST Quadrilateral RSTU, diagonals SU and RT intersect at point V. RSTU is a parallelogram. If m∠TSV = 31° and m∠SVT = 126°, explain how you can find the measure of ∠URV. Show all steps of your work, and refer to any properties of triangles, parallelograms, or triangle congruency theorems as necessary to justify your response.

The measure of <URV=

Step-by-step explanation:

From the given,

RSTU=parallelogram

SU and RT are diagonals meeting at point V

<TSV= and <SVT=

Therefore,

RS is parallel to UT (opposite sides of of parallelogram are congruent i.e. equal and parallel)If RS and UT are parallel, then <STV=<URV (alternate angles between two parallel lines are equal)But from ΔSTV, <STV=(sum of angles of a triangle equal )Therefor, <STV=<URV=: <URV=

Alternatively,

<RVU=<SUV=(opposite angel of a pair of bisecting lines are equal.<RUS=<TSU=(alternate angles between two parallel lines are equal:recall that RS is parallel to UT).Therefore, <URV=(sum of angles of a triangle equals .

Whatever approach, URV=
