Question

find the value of x if abllcd class 7?
​

Answer 1

Step-by-step explanation:

AB∥CD,CB is transversal

∴∠OBA=∠OCD (corresponding angles)

∴∠OAB=∠ODC (corresponding angles are equal)

△OAB & △ODC

∠BOA=∠COD (common angle)

∠OBA=∠OCD

∴ By AA corollary

△OAB∼△ODC

∴

DC

AB

=

OD

OA

⇒

5.49

1.83

=

6+x

x

⇒x=3m
