Verified Answer
In the figure, not drawn to scale, ACDF is a rectangle and BDE is a tr...
∠CDB+∠BDE = 90o
(Angle of a rectangle)
⇒ 48o+∠BDE = 90o
⇒ ∠BDE = 90o−48o = 42o
In ΔBED ∠EBD+∠BDE+∠BED = 180o
(Angle sum property)
⇒ 86o+42o+∠BED = 180o
⇒ ∠BED = 180o−(86o+42o) = 52o
(Angle of a rectangle)
⇒ 48o+∠BDE = 90o
⇒ ∠BDE = 90o−48o = 42o
In ΔBED ∠EBD+∠BDE+∠BED = 180o
(Angle sum property)
⇒ 86o+42o+∠BED = 180o
⇒ ∠BED = 180o−(86o+42o) = 52o
