Question

if angleACB =angleCDA and AC=6cm and AD=3cm then find the length of AB​

Answer 1

Answer:

AB=9

Step-by-step explanation:

from tringle ACB and tringle DCB,

angleCDB = angle ACB

angle B = angle B

BC = BC

so tringle ACB=~ tringle DCB

so AC=BD {CPCT}

so BD= 6cm

so AB = BD+ AD

= {6+3}cm

= 9 cm
