Question

in the figure if AD=6cm DB=9cm AE=8cm EC=12cm ADE=48° find
ABC​

Answer 1

Step-by-step explanation:

llease give the figure first

Answer 2

Bhai figure toh bhej deta!!!!!!!!

CHALO KOI NHI YELO ANSWER PAR BRAINLIEST MARK KRNA

Given : In ∆ABC,

AD = 6 cm , DB = 9 cm,

AE = 8 cm , EC = 12 cm

and <ADB = 48°

Now ,

AD/DB = 6/9 = 2/3 ---( 1 )

AE/EC = 8/12 = 2/3 ---( 2 )

From ( 1 ) & ( 2 ) ,

AD/DB = AE/EC

Therefore ,

DE // BC

[ By ,converse of Thales theorem ]

<ABC = <ADB = 48°

[ Corresponding angles ]
