23. In the figure above, segments RS and TU represent two positions of the same ladder leaning against the side SV of a wall. The length of TV is how much greater than the length of RV?
(1) The length of TU is 10 meters.
(2) The length of RV is 5 meters.

Here .. RS and TU represent two positions of the same ladder so RS = TU.

Stmnt 1 : TU = 10 => RS = 10

We can solve for TV & RV.

Stmnt 2.

RV = 5

calculate value of RS from this.

again RS = TU = x (whatever value we get)

solve for TV.
