Question

hi solve 9th sum.....
....​

Answer 1

it is easy

take angle PBA as X

and angle BPA is 90 subtract from 180 you will get angle BAP

BAP = 180-(90 +X)=90-X

since BC is the tangent so angle ABC is 90 so angle PBC=90-X

THEREFORE,angle PBC=angle BAP

Answer 2

angle(bad)=90

angle(abc)=90

angle(pab)=90/2

=45

(ac bisects angle(dab))

angle(pbc)=90/2

=45

(bd bisects angle(abc))

abgle(pab)=angle(pbc)=45
