Question

. From an external point P, tangents
PA and PB are drawn to a circle with
centre 0. If CD is the tangent to the
circle at a point E and PA = 14 cm, find
the perimeter of APCD.​

Answer 1

Answer:

PA=PB=10cm

CE=CA

DE=DB

Perimeter of ΔPCD is,

=PC+PD+CD

⇒PC+PD+CE+ED

⇒PC+PD+CA+DB

⇒(PC+CA)(PD+DB)

⇒PA+PB

⇒10+10

⇒20 cm.
