Answer 1

Answer:

Hope this helps.

BX = BZ      since these are tangents to the circle

CY = CZ      since these are tangents to the circle

AX = AY      since these are tangents to the circle

So perimeter of ABC

= AB + BC + AC

= AB + BZ + CZ + AC

= AB + BX + CY + AC

= AX + AY

= 2 AX

=> AX = (1/2) × perimeter of ABC
