Answer:

UV = 45 in , RS = 114 in

Step-by-step explanation:

A segment joining the midpoints of 2 sides of a triangle ( midsegments ) are half the length of the third side.

UV  is a midsegment , then

UV = [tex]\frac{1}{2}[/tex] RT = [tex]\frac{1}{2}[/tex] × 90 = 45 in

VW is a midsegment , then

RS = 2 VW = 2 × 57 = 114 in
