Why is the answer D? If both sides are same, doesn’t that mean that RS<2RT. Wouldn’t that mean RS<RT?

Can anyone help?

No (hint: try RS = 3 and RT = 2)

It only says that ST = RT.

X=Z that means RT= ST

the question is asking which is bigger RT OR RS

Well if it is right triangle, and Y=90 then RS must be bigger.

However, we do not have any information supports that.

In fact, we can change little bit.

It could be that y=14 and x=86 and z= 86, in this case RT is bigger.

Answer is D

Case I-

x=y=60 => z=60

ST=RT=SR.

Case II-

x=y=45 => z=90

RT is longest.

Hence D.
