Explanation:

Triangle DOE is isosceles. So OED and ODE has same angle.

Total angle for isosceles triangle is 180.

ODE + OED = 180 - 68 = 112

OED = ODE = 112 /2 = 56

Amir Hosseinzadeh · Answer 2 · 2023-02-03T03:28:42+0000

Answer:

EDC = 56 degrees

Explanation:

triangle OED is isosceles : base angles are congruent

2 * EDC + 68 = 180

2 * EDC = 180 - 68

2 * EDC = 112

2/2 EDC = 112/2

EDC = 56 degrees
