Answer:
70°
Explanation:
so a straight line is always going to be 180°
you're given the measurement of angle ZPB and APW
ZPB is 90° because it's got that little box, which means 90°
APW is 20°
so you would take the measure of your two given angles and add them
90+20=110
and then you would subtract that from 180, to find the missing angle
180-110=70
