The answer to your question, is 4 inches
hope this helps :D
The secant of a circle is any line that intersects two points on the circumference of the circle.
In the given circle, the lines EF and XY intersects two points on the circumference of the circle and hence are secants of the circle.
From the answer options given, the secant line is line XY.
Given the angle

angle

is equivalent to angle 135 degrees and angle 135 degrees is equvalent to angle 45 degrees in the second quadrant, thus sine is positive but cosine and tangent are negative.
Answer:
In order for line AE to equal line BF, m/DFB and m/CEA must both be 90°. When this occurs, line AB does not intersect line EF: the two lines are parallel. line AE and line BF represent the perpendicular distances between line AB and line CD. When the two lines are parallel, the perpendicular distance between them is the same throughout their length.
