Answer:

The length of RS is 47 units

Step-by-step explanation:

Midsegment Theorem

The midsegment of a trapezoid is a line segment that connects the midpoints of the non-parallel sides.

The length of the midsegment of a trapezoid is the average of the lengths of the bases.

The midsegment of the given trapezoid is VW, and the bases are RS and UT.

According to the midsegment theorem:

[tex]\displaystyle VW=\frac{RS+UT}{2}[/tex]

Substituting the variable lengths of the sides:

[tex]\displaystyle 3x+5=\frac{2x+15+6x-37}{2}[/tex]

Operating:

[tex]\displaystyle 3x+5=\frac{8x-22}{2}[/tex]

Dividing the fraction:

[tex]3x+5=4x-11[/tex]

Rearranging:

[tex]4x-3x=5+11[/tex]

Operating:

x=16

The length of RS is:

[tex]RS=2x+15=2*16+15=32+15=47[/tex]

The lenght of RS is 47 units
