Answer:

RV = 19

Step-by-step explanation:

You have a rectangle, therefore you need to know the following facts:

1. The diagonals are =

2. The diagonals bisect each other.

3. Opposite angles are =

RT = SU                  Diagonals are = in a rectangle

5x - 12 = 4x - 2        Solve for x

x - 12 = -2

x = -2 + 12

x = 10        Now you know RT = 5x - 12

                                           RT = 5(10) -12

                                           RT = 50 -12 = 38

Now diagonals of a rectangle bisects each other meaning this RT= RV + VT  and RV = VT  RT =38 so RV =19 and VT =19.

Next  m ∠SVT = 70°.  m ∠SVT = m ∠VUR are vertical angles are =  

RV = VT and SV = VU.  so ΔSVT = ΔVUR are congruent by SAS.  Thus

m ∠SVT = m ∠VUR   Corresponding parts of congruent triangles are ≅ (CPCTC)

These triangles are isosceles (two angles are = to each other.  

70°+ x° + x° = 180°; 70° + 2x = 180° ; 2x = 110°; x = 55°.    I hope this help.
