It is D

from statement 1: TU is the hypotenus of a 45,45,90 triangle x,x,x(sqrt2)
x = 10/(sqrt2) = TV

TU = SR
SR is the hypotenus of a 30,60,90 triangle
therefore RV = .5SR = 5

TV - RV = 10/(sqrt2) - 5

Suff

statement 2: is also suff using the reverse steps of statement 1

I missed the point that RS and TU represent two positions of the the same ladder, meaning that they have the same length. Thanks for detail explanation.

i get D too..and really didnt do any math here..

i know the angles..45-90-45..is an issoc triangle.. so TU=sqrt(2)X... TV=X

sufficient
