In a triangle PQR, PQ = x, RQ = y and PR = b. The height from PR to Q is h. What is the value of angle PQR?
1) xy = bh
2) angle R = 30 degrees

IMO A
bxh=X x Y
1/2 b x h = 1/2 X x Y
this means that x should be perpendicular to y angle pqr= 90

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
