Answer:
55
Step-by-step explanation:
we know that equals lengths of the curds makes equal angles at centre so
angle COD =110
and in triangle COD is an isosceles so the remaining angles are =(180-110)/2= 70/2= 35
that means angle OCP =35= angle ODP
in the triangles OPC and OPD
OC = OD(radius)
angle OCP = angle ODP
CP =DP(given)
so by SAS those two triangles are congruent
so the angle OPC = angle OPD
so OPC+OPD=180
OPC =180/2=90
so remaining angle = 180-90-35= 55
