Answer 1

Answer:

<bpa=90

<eab+<rba=90 because it is co interior angle

BP and AP bisect so,

<bap and <abp will be 45

therefore by angle sum property we would get

<bpa=90

hence proved

Answer 2

Answer:

90°

Step-by-step explanation:

ray n makes 90°with DE and RQ

THEN angle EAB=ANGLE RBA=90°

AP bisects ANGLE EAB IN TWO EQUAL ANGLES

SO PAB=45°AND IN THE SAME WAY ANGLE PBA=45°

THEREFORE PAB+PBA+APB=180°

45+45+APB=180

180-90=APB

90°= ANGLE APB
