Answer:

In the quadrilateral AzBCD add all the angles

x+70+3x-20+2x+5+2x-15=360

(husum of all 4 angles of a quadrilateral is 360 degree)

8x+40=360

8x=360-40=320

x=40

angle ABC=3x-20=3×40-20=100

APD=5x and APC=x (opposite angles)

Add all the 4 angles

5x+x+5x+x=360

12x=360

x=30

APD=5x=5×30=150

Do the last one in the same way as done the 1st one
