Answer 1

Answer:

In triangle OPQ

OP = OQ (radius of the same circle)

so,

Angle OPQ = Angle OQP ( angles opposite to equal sides are equal)

let angle OPQ = x

so, angle OQP = x

in triangle OPQ

Angle O + angle P + angle Q = 180°

60 +x+x = 180

2x = 180-60

2x= 120

x = 60

since all angles of this triangle are equal then it is an equilateral triangle.

so length of chord PQ = 8 cm
