Question

FIND THE VALUE OF x.

Answer 1

Step-by-step explanation:

angle OBC= 70° , angleOCB=60 °

In ∆ OBC = 180

70°+60° +angle BOC = 180

130° + angle BOC =180°

BoC = 180 -130= 50°

angle BOC =Angle EOD = 50° ( V.O.A)

Angle ECD = Angle OBC = 60° ( alternate angle)

50° + 60° + x = 180°

x = 180° - 110° = 70
