Question

Two parallel chords of a circle of radius 2 are at a distance apart. If the chords subtend at the centre, angles of and , where , then the value of is [note: denotes the largest integer less than or equal to​

Answer 1

Explanation:

If the chord subtend angles πk and 2πk at the center, where k>0, then the value of [k] is. Two parallel chords of a circle, which are on the same side of centre,subtend angles of 72∘and144∘ respetively at the centre Prove that the perpendicular distance between the chords is half the radius of the circle.

Answer 2

Explanation:

If the chord subtend angles πk and 2πk at the center, where k>0, then the value of [k] is. Two parallel chords of a circle, which are on the same side of centre,subtend angles of 72∘and144∘ respetively at the centre Prove that the perpendicular distance between the chords is half the radius of the circle.
