Answer:
n quadilateral ABCD,LET angle PAB=PAD=x,angle PBA=PBC=y;
angle A+angle B+angle C+angle D=360
angle PAD +angle PAB +angle PBA +angle PBC+angle C+angle D=360
x+x+y+y+100+60=360
2(x+y)+160=360
2(x+y)=360-160
2(x+y)=200
x+y=200/2
x+y=100
Now in triangle PAB;
angle PAB+angle PBA+angle APB=180
x+y+ angle P=180
100+angle P=180 (Since x+y=100)
angle P=180-100
angle P=80
