Question no.27. please

Answer 1

Hey Here Is Your Answer


Angle BAE = Angle DOE ( Corresponding angle)

So apply exterior angle property In triangle OEC

Angle ECO + Angle OEC = Angle ODE (exterior angle property)
Angle ECO + 20 = 65
Angle ECO = 65-20
Angle ECO = 45

SO ANGLE ECO = 45 DEGREE


I HOPE ITS HELPFULL FOR YOU.

IF IT HELPFULL FOR YOU THAN MARK AS A BRAINLIST.
