Aline which passes through at least two points of a curve

A line which passes through at least two points of a curve is called secant line.

Step-by-step explanation:

Consider the provided statement.

A secant, is a line that passes through two curve points.

It connects two points in the Cartesian plane on a curve where the curve can be describe by a function.

A secant line commonly refers to a line that intersects a circle at exactly two points.

Remember: The secant line is almost the same as a tangent line when two points are closed together.

Hence, A line which passes through at least two points of a curve is called secant line.

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
