Answer:
,........!/…………………3+3++478301?&3)
Step-by-step explanation:
Since AB = AC,
Angle ABC = Angle ACB - eq 1
Since BD = CD,
Angle DBC = Angle DCB - eq 2
Subtract eq 1 - eq 2
You will get,
Angle ABC - Angle DBC = Angle ACB - DCB
Which implies
Angle ABD = Angle ACD
As both are equal,
ABD/ACD = 1
HENCE PROVED. Lol
