In the figure below, ZAPE and ZEPD are congruent.
Taya2010 [7]

Answer:

54degrees

Step-by-step explanation:

From the given diagram;

2<P + 136 + 74 + 42  = 360 (sum of angle at a point is 360degrees)

2<P +252 = 360

2<P = 360 - 252

2<P = 108

<P = 108/2

<P = 54

Hence the measure of <P is 54degrees
