All numbers used are real numbers. . A figure accompanying a problem solving question is intended to provide information useful in solving the problem. Straight lines may sometimes appear jagged. All figures lie on a plane unless otherwise indicated. You have to decide whether the data given in the statements are sufficient for answering the question.
All numbers used are real numbers. .
A figure accompanying a data sufficiency problem will conform to the information given in the question. Lines shown as straight can be assumed to be straight and lines that appear jagged can also be assumed to be straight. You may assume that positions of points, angles, regions, etc., exist in the order shown and that angle measures are greater than zero. All figures lie in a plane unless otherwise indicated. . In data sufficiency problems that ask you for the value of a quantity the data given in the statements are sufficient only when it is possible to determine exactly one numerical value for the quantity. .
