(1) The length of segment PQ is twice the length of segment QR
(2) a = 9

Property:Triangle drawn in Semicircle is always Right angle triangle hence PQR is right angle triangle
Property: In right traingle, a perpendicular dropped from right angle vertex on hypotenuse divides the triangles in to two similar right angle triangles and all right angle triangles will be similar


Question: What is the value of b/c?
i.e. we need ratio of shorter and longer bases of right triangle
Since all triangles here are similar so the corresponding ratio in any triangle will do good

Statement 1: The length of segment PQ is twice the length of segment QR
i.e. b/c = 2/1
SUFFICIENT

STatement 2: a = 9
NOT SUFFICIENT

Answer:option A
