\angle PCD=40^{\circ}

Step-by-step explanation:

Center of the circle=p

Two chords AB  and CD

AB=CD

Angle APB=100 degrees

We know that

Equal chords subtended equal at center of circle.

Therefore, angle APB=Angle CPD=100 degrees

PC=PD=Radius of circle

Let angle PCD=angle PDC=x

Angle made by equal sides are equal.

In triangle PCD

\angle PCD+\angle CDP+\angle CPD=180^{\circ}

Using triangle angles sum property

Substitute the values then, we get

x+x+100=180

2x=180-100=80

x=\frac{80}{2}=40

\angle PCD=40^{\circ}
