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.

IMO - C but OA is D

Hey TU =10 is nothing but the length of the ladder
so use 45-45-90 & 30-60-90 triangle ratios to find other sides & get the difference (one side knaown)

SUFF

(2) The length of RV is 5 meters.

Same here also

Sure sir! I will rather use spoiler to provide the IMO and OA. Is it fine?
