Step-by-step explanation:
angle B+angle C+angle A=180'[angle sum property]
angle A=180-[30'+96]
=180-126
=54degree
In triangleAPB
angleABP=30/2 =15' [BP is bisector of angle B]
angleBAP=54/2 =27' [AP is bisectorof angleA]
angleBAP+angleABP+angle APB=180 [angle sum property]
27+ 15+angle APB= 180
angleAPB=180-42
angleAPB= 138'
