Angle AD is 128 and since it’s on the same line it adds up to 180 so angle CD would be 180-128=52

Answer:

Measure of CD = 52°

Step-by-step explanation:

In a circle P, AC is the diameter.

We have to find the measure of arc CD.

Since ∠DPC + ∠APD = 180° (supplementary angles)

∠DPC + 128 = 180

∠DPC = 180 - 128 = 52°

Therefore the length of arc CD will be = 52°
