anglePCA

Step-by-step explanation:

construction ; join OC

angle CAB= 30° (given)

angle ACB =90 ( angle in a semicircle)

angle PCO= angle PCA+ angle ACO

anglePCO =90( tangent to the circle is perpendicularto the radius to point                                     contact )

90°-30° = 60° = angle PCA
