The Figure Shows a Right-Angled Construction Frame ABC

The figure shows a right-angled construction frame ABC.When measured at rest,it has dimensions as follows: AB = 26.0 m,AC = 10.0 m,and BC = 24.0 m.This frame is now given a new velocity of 0.760c,relative to Earth,in a direction parallel to AC.How long is part AC of this frame with the new velocity as measured by Earth-based engineers?

A) 6.50 m
B) 25.4 m
C) 24.3 m
D) 23.7 m
E) 24.9 m
