Question

In the given fig ab is parallel to cd find the value of x

Answer 1

Answer:

54°

Step-by-step explanation:

Extend the line EC , Now angles ECD and EFB are corresponding angles of parallel lines so

EFB = 114° .

Note that Angle EFB is "Exterior angle of triangle ∆EAF" [ Gogle it if you want to know more ] , so it's equal to sum of other two angles , so

$60 + x = 114 \\ x = 114 -60 = 54$

Answer 2

Step-by-step explanation:

given :

• In the given fig ab is parallel to cd find the value of x

to find :

• find the value of x

solution :

• 105° + ZAEC+ZCEF = 180⁰

• >114° - 60° (180° – x°)

• 54 = x = 180°

• hence x= 54
