Question

a chord of radius 6cm with angle 60 at center find length of chord​

Answer 1

Answer:

6 cm

Step-by-step explanation:

given,

radius of the circle=6cm

angle made by the chord at the center=60°

let the other angles in the triangle be x because the radii of the circle are equal

we know that,

sum of the angles in the triangle=180°

=>x+x+60°=180°

=>2x+60°=180°

=>2x=120°

=>x=60°

such that given triangle is equilateral triangle.

hence, in the equilateral triangle all sides are equal.

chord of the circle is 6 cm

Answer 2

Answer:

x+x+60°=180°

2x+60°=180°

2x=120°

x=60°

chord of the circle is 6cm
