Hi all. Please help me with these questions. I don't understand how they go to the answer. The ones that I got right was guess work. Thank you for your help

Option 1 . t<0. Clearly both t and k must be negative. So the kt is positive and hence to the right of t

Option 2. k<1. We have three options. 0<k<1. In this case kt will be in between k and t. k=0. In this case it will be as same as k. k<0. This can be negative if t is +ve. It can go to the right of t if both k and t are negative.

So clearly a.

Take the full triangle.

LP + LR + LT = 180 LR + LT = 90. since LP = 90. -------(1)

In isosceles triangle RQS, LRSQ = LRQS Hence Sum of angles in triangle RQS LR + LRQS + LRSQ = 180 LR = 180 - 2(LRSQ) --------------(2) since LRSQ = LRQS

Hey dude... Am no expert man... Am giving my gmat on nov 22. Me too in ur range.

One thing i noticed in similar problems like 1st qstn.

We need to first rephrase the entire triangle and then if we narrow down we will arrive at the answer. If we start from the unknown, then we will be lost. This approach helped me in many similar qstns.
