Question

In the given figure, ABC is a triangle and DEFG is a rectangle.

∠ABC = 180 − 82 − -------------- = -------------------

Since DEFG is a rectangle, so ∠DGB = -----------------

Hence, Angle sum property in triangle DBG will give,

∠BDG = 180 − 90 − -------------------------- = --------------

So, ∠ADE = 180 − 90 − ---------- = ==========

Answer 1

180-82 = 98

180 - 90 = 90

so, 180-90=90
