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
