Answer and Explanation
Your Answer is
Correct Answer is D
Explanation
The length of PQ is the addition of the radii of the two circles and then subtracting the overlapping part, which is XY, so PQ=PB+BQ-XY=9+12-2=19, so choose D
55. In the figure below, the circles centered at P and Q intersect at A and B, and points P, X, Y, and Q are collinear. The lengths of PB, QB and XY are 9, 12, and 2 units, respectively. What is the length, in units, of PQ?
