Answer 1

Answer:

Step-by-step explanation:

Draw perpendicular bisector of AB

∠DCE = 84°

Step-by-step explanation:

ABC is isosceles triangle with AC = BC

so to divide  into two parts of equal area

we can draw a perpendicular bisector of AB

which will pass through point C as AC = BC

Let say perpendicular bisector of AB bisect at O

then Area of Δ AOC = Area of Δ BOC = (1/2) Area of Δ ABC

∠DCE = ∠ACB  ( opposite angle)

∠BAC = ∠ABC   ( as AC = BC)

∠BAC = 48°

∠ABC + ∠BAC  + ∠ACB = 180°  ( Sum of Angles of a Triangle)

48° + 48° + ∠ACB = 180°

∠ACB = 84°

∠DCE = 84°
